Hey guys, I originally asked this question in the "general engine" forum but I got no answers. So I thought I'd try this forum. Thanks!

It can be done search on the TPI section.https://www.thirdgen.org/forums/tpi/...e-350-tpi.html

yeah it can be done yes but i think the bolt holes dont line up probably a pain in the a**. u got to take heads to a machine shop and close bolt holes and drill new ones.

It would not even be worth the effort if you weren't doing significant mods to the rest of the engine while you were at it.

yeah the lt1 intakes dont flow very good the design alows the front cylinders to recieve more air flow than the rear so wouldnt be worrh the trouble.

Thats a wash. The LT1 intake was one of GMs best flowing stock intakes as seen by the number of 4th gens who never upgrade more than some mild porting even in the very high power levels

Cyl 7/8 lean conditions are present on ALL front inlet log style manifolds. TPI, LT1 and all LS series have this flaw. The only remedy is switching to a center inlet like a single plane EFI manifold. Your tuner will be able to cope with this minor setback

The intake like ANY intake upgrade is a supporting mod for things like cam and heads

Theres more to it than redrilling the manifold bolt pattern but its far from impossible. That site is closed BTW, do a search on the site and youll see several people have intakes sitting there for better than a year

I have the intake and would recommend it to anyone, plus it looks killer

seems to be more trouble than its worth to me...just my .02 cents

TexasLT1

no, that's not what I meant

wtf r u laughin at the lt1 design allows more air to flow to the front cylinders and that engine bay looks like something out of a junk yard and the lt1 intake swap aint worth it unless u want one just because

TexasLT1

And as Pocket already mentioned, how is that ANY different than the TPI, the TPIS Mini Ram, Ram Jet, or Stealth Ram?

My original point was that, if the intake was the only mod being performed on the 305, it would be pointless to go through the work required to put the LT1 intake on because the heads flow so horribly, the cam sucks, and the exhaust would be exhaling through a straw.

WITH those mods, the intake would be WELL worth the effort due to the increased flow over the, I'm assuming, TBI intake, and still a better intake for horsepower than a stock TPI intake.

Gads, a Stealth Ram is so much easier, and I can't imagine how it could be more expensive than going through an LT1 mod for a Gen I engine.

jm84z28

i get your point but there are mod u can do better than the lt1 intake and probably less of a pain in the a** and on the power curve talk yeah will probably give 5 hp more over the tpi but more than likely less torque but idc

Used HSR vs preconverted LT1, the LT1 is a few dollars cheaper in most cases. New HSR vs self converted LT1, its pennies on the dollar. My swap cost me around $400 with the preconversion, remote t-stat and powdercoating. A bare HSR will run you atleast that

I dropped 3 tenths on the 1/8 with just the intake swap on a L98. 5hp is a bit low. When I was doing the research, most reported 40-50hp increase with around the same lost in tq without the LTR setup of TPI. Will a stock 305 like the intake? Most likely you wont feel a difference. Will a modded 350 feel it? Definately

Maybe I'm a little slow, but I didn't get the impression this was a do-it-yourself project. Or that an LT1 intake was in-hand.

nope buddy was just wondering i think and then turned itno a debate

its not a remove and replace project, thats for sure.

and perhaps a efi vic with a 90*elbow would cost about the same and have better hp potential and bolt on. not sure its worth the mod on a 305 unless the motor is forced induction.

Brendan91Z

why go through all the trouble why not just dump a lt1 in it instead of the 305?

jm84z28

iTrader: (1)

that would be to e z lol

Brendan91Z

true to me it just sounds like a better idea you probably spend less time doing that lol

jm84z28

iTrader: (1)

true but if he did that we all couldnt look like idiots argueing
