I'm putting the parts together to do a H/C on a 93 350. I'm using the vortec heads, but according to Comp cams, I will be limited to a rather anemic cam because of the limitations of the chip. I have a couple of modified LS1 cars that I had the PCM edited to compensate for the mods. Is there anyone that is doing this with th earlier chips?

Thanks

 

i did a 93 truck, what are you using for induction...........Turbo City does a ton of Tbi mods, go ahead and as questions, ihave a ton of info

 

they actually specialize in vortec tbi conversion, they sell a full kit, tbi, manifold, chip, etc.......

 

I'm planning on going with an Eldebrock intake with the holley TBI adapter. I plan on doing the TBI modifications to get a little more flow.
I'm not interested in a radical cam because it's a daily driver, but CC said I would be limited to about a 206/210 degree at .050, which is not much more than stock.
I guess I should contact TC and see what the can do for me.
Thanks

 

turbo city knows their stuff, call 'em up, and talk to tom. And do not, i repeat, do not buy the holley projection 670 cfm throttle body, under no circumstances. it's a piece of crap, and all you'll have is drivability issues. Tom knows his stuff, buy what he tells you to, and they'll make a chip for your application. btw, you can go with a much bigger cam... I think tom says 210 duration on intake is the max to go, and exhaust doesn't matter. but i had a bigger one, worked fine on stock heads. vortec heads might be dif. remember, with the vortec heads you have to do egr modifications to your headers or manifolds.
