I have a stock base off of my 89 IROC that I spend quite a bit of time on porting and matching to my SLP runners. My car pulled strong up to 5500 RPM with this base. There are no stripped threads or problems with the base. It was a big improvement over the stock porting. $100 plus shipping. Email Fastmax@cfl.rr.com

 

wow I am in love. Talk about a super sleeper. Ill keep you in mind as my money rolls in. I have a built 355 and the cam is a beast out of the hole and dont spin much farther past the 5500 rpm's range. You willing to trade anything for these runners?

 

I would really prefer to just sell it, but if you want to PM me with what you have to trade I will surely look at it.

$75 shipped to 60007? paypal ready

 

I will keep it for that, I have too much time and effort into it. If you go the $100 I will go ahead and pay for the shipping.

Will stock runners blot up to it?

 

Thats a good question I hadnt really thought about but I believe the answer is yes they will. I put a set of stock gaskets up against the intake and it overhangs about 1/16" all the way around. I laid the gasket up against my old stock runners and it appears there is still plenty of sealing area. I cant really see where it would be a problem.

hey do you still have the base available?
