roller lifters will run in the neighborhood of 250-400 depending on brand and quality and those are the retro fit style that can be used in your block. i would even go as far as saying find a nice take out cam from something like a vortec or ram jet 350.

might as well go for the "package" and do the vortec heads and intake and the cam. I kinda agree, you have to remove the intake and valve covers anyway to do "just" a cam.
#Pulling cam 350 chevy mods#
In my case, mods are performed as funds become available. then you can gauge EXACTLY what part gave you what gains. However I do understand doing mods 1 at a time. You will notice a gain, but a lot of components must come apart again if you wanted to do other mods in the future.
#Pulling cam 350 chevy install#
I personally think that I might be disappointed if I did all that work to install a cam. Aluminum L98 heads will also just bolt on. I would save up a little extra money and get a better flowing/ported intake, and vortec or ported stock heads. personally I wouldnt JUST do a cam in a TBI truck.

Its tough to JUST do a cam, when you have 1/2 of the front end of the truck apart. The TBI/Vortec intake allows for the TBI unit to still be used, so its still a TBI engine at heart.
#Pulling cam 350 chevy full#
I see what you are saying, a simple cam swap turns into a full on engine retrofit. You just wanted a cam,and these guy's got you buyying a new motor. You can easily tell because there will be a sheetmetal spider assembly that keeps the lifters from rotating in their bores. Sometimes when folks pull the intake manifold, they discover that the engine ALLREADY has a roller cam in it. Vortec heads, cam, and chip will turn your TBI 350 into a very nice and powerfull all around driveable engine. Here is a pic of the TBI/Vortec intake manifold that allows you to run Vortec heads using your existing TBI injection system. parts book, along with all other camsīoosted Z71 of this forum is running a stock LT4 production cam in his 87 or 88 TBI truck(2nd and 3rd cam in the list above). Here is a copy paste list I supplied in teh Marien Intake thread for stock GM camshafts Usually when comparing a roller hydraulic and flat tappet cam to each other, if the duration numbers are the same, the hydraulic roller cam is usually more agressive. 412"/.429" lift for sure, and I know the TBI cam is smaller. I am pretty sure the TBI 350 engines use a cam with high. I would get either an 88-91/92 Vette or Fbodyor a 96-02 block as these are roller cam equipped blocks. You can also specify a roller block with the cam you want installed for a couple hundred more. By doing this you will get a couple more cubes from the bore, can get a bit more compression if you want, and will get superior heads. Going this deep into it, it would be better to go ahead and pick up a rebuilt 350 from a reliable engine shop, should be able to get a long block with Vortec heads for a grand, would then need a Vortec/TBI intake for 200 more.

putting a new top end on an old bottom end usually results in the bottom end taking a dump within a year or so if you like getting into it.

The block will have to be machined for it though, otherwise you have to use a very expensive retrofit kit. If at all possible, try to use a roller cam with roller lifters. Had excellent luck with a 252 cam in a 305, for a 350 I'd suggest a 258 or a 262 or 268 for a street/strip. I like Comp cams for a street engine, and have no use for any other kind of engine. If you put a decent set of heads on you would see a massive power increase with the cam you have.Ĭams are rated by RPM power, so you need to decide what RPM you will be in the most, and what the overall use of the vehicle will be. No real use in swapping the cam, because tbi heads are the real problem.
