I have 85 CORVETTE with stock motor, I'm in the process of putting on 1989 stock aluminum heads and I will replace the runners with TPIS runners. Will I need to replace the stock manifold with an updated one? Don't know if the bolt pattern will effect this conversion.
Hi Bob,
where did you get the runners from, are they new or second hand ?
The only difference you need to worry about first up is the 9th or cold start injector (which 85's are fitted with), do your runners have this provision ?
dont worry about the chip, the 85 computer and MAF can handle a lot of mods.

One from Ebay the other from AZ Speed.It does have the correct provison for the cold start. Will I need a new manifold?
