Hi I have a 90 Camaro IROC-Z 305 tpi automatic and I want to know if theres anything I need to change to run my tpi setup on a 5.7 vortec any help????Fuel Injectors?Motor mounts?Headers(I have Edelbrock TES)?Cam suggestions?Lifters?Push rods?Roller rockers?Any special tunning requiered for proper operation?

It's a daily driver. I have a mild 700r-4 with 2400 stall .

I will appreciate your help Thanks.

 

What kind of Vortec engine is this? To run your TPI on a gen 1 sbc with Vortec heads, you'll need to get the vortec base from edelbrock or soggy dickens (same thing). You will need to upgrade your injectors to 5.7L injectors. While you're in there, I would suggest you get a meaner cam. Something mild like the stock LT1 cam will be a nice upgrade, yet will be cheap and will work wih your stock ecm. Motor mounts and headers will still work. You will need to get your computer tuned to handle the extra displacement. Good luck!

 

Thanks Man ..I was thinkin late 9o's Vortec from a truck or something .What about a lt4 hot cam???Will that work properly?

 

I'm not entirely sure, but I think a late 90's truck vortec might be a different animal altogether. If that is the case, you're in for a very expensive and time consuming swap. For instance, the LQ9 block from a late model truck is basically a cast iron LS1--so it would be like swapping in an LS1. Great for performance, but not great for your budget (you can't re-use anything from your stock engine). Do a search on it, I know I've read articles about late model Silverado/Tahoe/Suburban vortec swaps.

You might want to think about upgrading to a 350 SBC and throwing some vortec heads on it. Dyno Don runs 12's with that setup and still gets 25mpg. You get to keep your computer and TPI that way, too. That's the route I plan to take this summer

 

Late 90's Vortec truck V8's were of the Gen I type.

The LT4 Hot Cam would have too much lift for stock, unmodified Vortec heads.

 

Well in that case I have some research to do.So what year 350 would you recommend me getting?Thanks for the info so far man

 

This takes care of the engine and base:

You still need runners and TB. Your headers should be okay.

Or, you can build it yourself. As already noted, the Hot Cam will require head upgrades - the crate has it.

Building it will probably end up costing about the same as the crate, though.

 

That motor looks bad man I would like to have that under my hood.But okay lets see here my plans were to hopefully adding a Procharger to it.That shouldn't be to much of a problem rite???

 

That's not a question for me. The Power Adder forum would be a better place for that question.

 

Nice Im just so excited I cant wait till I get my money together and just spend it on my IROC-Z
