Lightbulb Pontiac 301 Engine

Hey Everyone,, i have a question about a 1980 Pontiac 301 Engine Non-Turbo, i was just wondering if that engine could accutally make the Firebird Or Trans'am bury it's speedometer, meaning could it make the firebird or trans'am do at least 120 miles per hour, or if you could also recommend a site where i could pick-up a TurboCharger for that engine please do so...

Thanks For The Help..

Drop in a 455. The 301 was not a good engine even with the turbo.

I would have to agree with deleteall here.The 301 is the most pathetic V8 Pontiac ever produced. Your dealing with low compression, terrible heads, thin cylinder walls and a very weak bottem-end. I would suppose that with enough money any engine could put out good power, but would it really be worth it. There are countless engine swaps that you could do, so I would dig in and look for the best bang for my buck. Good Luck and Happy Hot-Rodding!

Your Firebird should be able to handle the 455 just fine. Just make sure that your trans and rear end are up to snuff. Also you will need to install stiffer springs on the front. As far as power is concerned, that depends on whether or not you leave it stock. 455s are known for torque so you will have an impressive take-off regardless of what changes that you make to the engine.

The tired old 301

Hey there Thuggish,

To answer your questions, the 301 for extreme high performance is ofcourse not quite the right option. An SD 455, or 400 Ram Air IV can give you much more bang for your buck. Just keep an eye on that Tach though. The huge mains in pointiac engines have a tendancy to burn the oil out of the bearings at engine speeds above 6000 revs. This 6000 RPM limit however does not apply to the 287, 317, 347, 303, and 301 engines, as they have 2.5" mains. Instead of 3" or 3.25". Power out of a R.A 4 400 or an SD 455 can be expected in the 3-400's hp range depending on how you build it.

The original person who asked this question ... has not posted in 2 years ... so this is a non issue IMHO and the question itself is OLD ...

sleeve it and bore it to 4.062
keep the 3.75 crank and BAM

a 301 can exceed 150 mph with the right gearing.... but would take you an hour to get there!!!!!!!
