Wanting to know how much it cost to port a set of heads for a lt1? how much hp gain am i looking at? whats yalls opinions on a tci breakaway stall convertor (2800 stall) for a Cc306 cam? i know its small.
With the right cam, AND expert assembly and tuning, you'd be looking at around 375-390 rwhp through an A4 with the $900 heads, and 400-430 with the AI $1800 heads.
I'm running the AI 200cc ported stock castings with a smallish 228 dur cam and put down 425 SAE through the A4.
You already know my opinion of that TCI TC .....and it has nothing to do with it being "small".
