Pontiac 301 turbo turbocharged 4.9 draw through carburetor plenum intake manifold trans am formula 

My buddy raced against one of these Trans Ams in his Ford F-100 that had a straight six and column shifted 3 speed. I couldn't believe it when we pulled ahead of the Pontiac by a car length and the truck just kept pulling away.

One of my friends had the 1981 Turbo TA. He would tout the turbo 301 & rave about the boost gage until he lined up against 455 SD TA. All we saw was the smoke from the SD's tires & tail lights. The Turbo TA got blown away.

I love all that late 70s and early 80s gm stuff, thanks for showing it all!.

the problem whit the 301T they started making power at 3000 rpm and the engine would rev only to 4800 rpm

That is one funky setup, it looks like there's tons of room for improvement tho. You could improve upon every aspect of that induction system with porting or custom manifolds. I wouldn't be surprised if just a work over of the manifolds, turbo and exhaust without even getting into the engine you could gain 50hp or more? And some basic head porting and a cam you could easily put it over 300hp...

It's a shame that people don't make performance parts for the 301

The Carbureted Turbo Buick V6 was nearly Identical in design. - GM was *TRYING* to make power from small engines.

I have a fresh 301 and a trany with a clean 79 I really want to find that manifold so I can put it together and get use out of that engine it's dynod at 227 so I imagine that will add sum spunk to it ...if I can't find one at a junk yard near albuquerque I'll just go with blow through but I really don't feel experienced enough to tune that setup seems draw through is simple enough to get right it's this or nos but that' will just munch that motor I'd like to have it run good enough to have mom tak it to work she wants newer muscle car but I am sticking on stupid and working with what I have this vid helped me visualize the set up thank you I really don't want to pull the 400 out of my lemans for the firechicken

Just saw a video where a stock 301 turbo TA did a 14.8 1/4 mile at 93 miles an hour. I think the boost was increased from stock slightly

It’s amazing how they managed to Ram all the air through that little 2-1/4 hole 🕳 in the intake. I guessing if they went larger they would lose too much low end torque.

Omg I am having flash backs from having this motor in my 80 transam ... what a junk engine not worth it ... anyway great content you got my sub

You do have your facts straight., Now, what's your "opinion" on the motor? Over-all?
