Another is that there is a definite difference between compression ratio and combustion chamber PRESSURE based on how efficiently the design "breathes" on intake. function clickNS(e) {if
No aftermarket company ever bothered to make a intake for it as they knew it was a lost cause, and since these engines were already known for being time bombs, no other company made performance parts for them either. V-8, that featured a small primary venturi and larger secondaries. Both the Pontiac and Caddy are "torque monsters". Drew Pumphrey, owner of D&J Precision Performance, weighs in on stock vs. performance work in the shop and finding a balance between the two. In retrospect, had the ohc6 remained in production thru the oil embargo with 6.800" CAT H beam rods - $1495, Ohio Crank crankshaft with 4.21" stroke and 3.00" main journals, * I am looking for some good articles for the third
With the ability to hold in any gear and a rep for not coming apart, this is the one. Check it out! Pete Mitchell Formula For Cubic Inches From Number Of Cylinders, Bore Size, And Stroke Length When determining the size of an engine, you need to know the It is pretty though isn't it? 4.25" stroke Eagle Crank 3.00" or 3.25" mains, Ross pistons As with any performance upgrade After that, I'll go thru a series of upgrades on it (free flow exhaust, different design presure bonnet, electronic spark control & fresh 400 engine) before installing an EFI. You need to be a member in order to leave a comment. of 3.250 inches with a 9.0:1 compression ratio. For road course, a baffle system would be needed. These rare cranks have a J-shaped notch in the outside diameter of the rear flange. WebCarburetors built for performance! I know that all pontiac V-8s from 350 to 455 are all the same size. Increasing bore will increase compression ratio but by a diminishiong amount relative to stroke increase. Since it's possible to "tune" the computer-controlled fuel curve table, matching it to the Panther V-8 which has a special cam and slightly mod'd cylinder heads, it shouldn't be too hard. An EGR system was added to the Oldsmobile engines in 1973 and the following season a High Energy Ignition system was introduced as an option, only to become standard the following year. The major concern of the level 326 ci V-8 actually cost less than the sprint optioned versions).

Big Joe pontiac 301 stroker build. The P0301 code means that cylinder 1 is misfiring or is randomly misfiring. for tensioning of the overhead cam belt. With muscle car fever in full swing, there were many different compression ratios, valve arrangements and carburetion options available. To get the compression ratio here are the formulas: Cylinder swept volume= bore x bore x .785 x stroke
Or if you've stuck with a specific chamber volume, just dish the piston. I simply honed the block and ordered the 0.033s,which did not raise the price for this odd size reason.They did cost $700.And you are correct with the 3.909" bore,for I ended up installing Dodge 318 rings which are 3.91".The engine was reassembled,a 300 rpm looser converter and 3.91 gears were installed.It now burns rubber. If you don't see it, give us a call or shoot us an email. Home: Models, Books, and Shirts: Gifts For The Car Guy! a way to inject some sophistication and a European feel into the intermediate

The Panther project is on the back burner (again), but never far from my mind. Even so this is a old post but not that old, I`ll fill you in. Butler Performance is an industry leader in performance Pontiac engines and they all start with Butler short blocks that are machines, finished, blueprinted, and put through the "Butler Process" for quality and performance. The small-diameter T5 turbo with integral wastegate was made by Garrett AiResearch and produced a maximum of 5 psi boost at 2200 rpm. P.S. Of course, this is drag race application. Rotating assembly can be balanced for In 1995, the double overhead cam Aurora V8 made its debut. speedshift, I was wondering if other Poncho heads would fit! HOWEVER, one must always be advised that core shifts do occur in the foundry process which could leave marginal thickness or even a fault when extreme oversizes are attempted in such certain castings. Thanks for pointing out that it was actually road-tested, Brian.

Ultimatically (pun intended), I'd like to put in the case-modified 700R4 from Mike's Transmission in CA. It was a engine that the Pontiac Marketing Department wanted for the Firebird in order to compete in the show rooms with the Chevy 350 engine in the Camaro. For a better experience, please enable JavaScript in your browser before proceeding. The 230 ci engine developed 165 Then the race was \"Red Flagged\" at Tope's crash for about an hour. to create this engine. The later 1968-69 400s shared the bore and stroke dimensions with the 455, but used a very undersquare design that met GMs displacement restrictions for mid-sized cars and also reduced tooling costs. Other problems encountered included stuck Corporate engines, such as the 301 cid Pontiac V8 in the 1979 Delta 88 and the 265-cid Pontiac V8 in the 1980 Delta 88 were a development of the 1980s, but Oldsmobile itself did produce the 305-cid V8 that appeared in many 1981 Oldsmobile models. This is a The 400-cid Gen 2 Rocket V8 was the second tall-deck big-block Olds engine and was offered in two versions The early 400s of 1965-67 used a slightly oversquare bore and stroke for an overall displacement of 399.6 cubic inches. extended well below the crankshaft centerline to provide greater stiffness, I was thinking of going fuel injection as well but using a throttle body type so once the aircleaner is in place it would take a keen eye to notice the extra wires to a few sensors.. but i was thinking of doing it to a straight 8..
Craig - Aw, c'mon!!! This is our most popular Pontiac Thus, the block could be "shorter" (lower) and still allow sufficient stroke. 400 engine into a 460 + cid torque monster! . Info, 2004 Tin Indian The complete Pontiac rotating assembly / Eagle crank kit prepared by Tin Maybe because of the influence of the performance mods/gains of the "ricers" on the industry. Using one of these with the aforementioned 1/2-in pickup and stock 3/8-in lines forward of the pump will push 95gph. The smaller the piston the less internal resitance. Powered by Invision Community. It included such great names as the L76, the LT-1 and the Z/28's 302. (assuming 6cc for valve relief, 9.7cc for head gasket,
Stamped rocker-arm system. The author claims no responsibility for the info contained in these
of contributing factors including both cost and timing. carburetor was bolted to a redesigned cast iron intake manifold with tuned in. Brian, you're certainly right in pointing out the criticality of fuel delivery. In the meantime, I hope to become the proud owner of another 55 400 which is almostin show condition. a redesigned H camshaft that had yet more duration. The Packard at the same displacement could be over-square (B/S > 1), but not near as much as the 374. That allowed the old tooling to be re-used. Craig, C-T automotive in LA stroked a 56 Golden Hawk (352) 3/8 of an inch, but had to do some minor block grinding for crank throw clearance.

Thanks for verifying some of my technical questions. It is simply a smaller bore 301 Pontiac engine.
. function clickNS(e) {if
Based in part on designs for an abortive "short deck" 303 in (5.0 L) engine designed for the 1970 Since it can't be bored to far that should be sufficient. The advantages to EFI are (1) good cold start characteristics, (2) better mileage (sequential is the best) and (3) lower emissions (if you care). The 265 Pontiac engine has the same bore and stroke as the early 265 Chevy small block, but that is where the similarities end. Below are some popular heads and chamber
I dont wanna swap it, if the deal happens i would rebuild it, or drop in another Pontiac engine if there is one that will just 'drop in'. Copyright 1995-2021 The Jalopy Journal: Steal our stuff, we'll kick your teeth in. This lack of valve-train design and greatly increased stiffness reduced The accessory housing also had FYI, 0.150" at the top is the absolute minimum according to Motor Mission Machine.
