Ok, did a search and there was too much info!!
I have a simple question: What are the differences between the 97 Chevy truck Vortec engines and the L98 engines? i know the heads are different and will require a new Base to use my TPI stuff and I know the serpentine brackets will not work, but is everything else in the right place?
Thanks!!!

 

I suppose I should clarify a few things: The car I am thinking of putting it in is an '86 IROC, and the engine in question is a 350 Vortec from a 97 Chevy tahoe.

 

Er... Anyone?

 

yea everythings the same... i have a vortec350 in my 83 ta and all the stock brackets bolt right up

 

Good deal!! I am right, that I will need a new base to use my TPI, right?

 

Yea, and the vortec TPI base is a pricey piece...

 

How pricy, and where do I find it? I have been looking and havent found it.

 

Summit Racing or Jegs will have it. Edelbrock makes them. Usually about $470 or so.

 

Ah, Thats not too bad.

 

Ok, I guess I will modify this a bit and ask: Who makes TPI bases for vortec heads and which is the best one?

 

And what about a roller cam? Something kind of radical, but still streetable.

 

Ok, the only thing I am missing is the cam... I want to stay with a lift the stock heads will handle without any machine work. (I'm not opposed to changing the springs, though.)
Thanks!

 

I'm thinking about doing this but just using the stock vortec stuff. My car is a TBI though so I don't have anything worthwhile to swap over.

 

Check out the thread I just posted. Im running a 97 vortec motor in my 88. I just installed a LT4 Hotcam. I was able to do get by with the lift problems without pulling the heads. I love that cam. I however am running a carb, so you will have to retune your computer for the new cam.

If you want to keep with the TPI, go with the Edelbrock IMO
