88 GT Cam help

Unless it was originally sold in California or was later converted to mass-air by someone, the answer is no. Speed density computer systems

-- likely what your car is running -- do not like cam changes. Basically, any cam other than a stock unit will have your car idling like crap.

But don't be bummed. The stock cam is a good one for the stock heads/intake. If your going to do a cam change your best bet is to match it with a new set of heads and an intake and do all three at the same time.

But you still want to do something to add a few extra ponies, right? Here's what you do: Buy a set of 1.6 or 1.7 roller rockers. They'll give you a bit more lift/horsepower and your speed density computer will stay happy. But being that your car is an '88 (how many miles do you have on it?), it probably needs a set of new valve springs. Get some new stock unit.

Patrick is correct. This was exactly what I did with my '88 GT:

-equal length shorty headers

-1/2 inch intake spacer

-off-raod pipe

-1.7 Cobra Roller Rockers

-new valve springs and pushrods from Summit

-new 190Lp fuel pump

-K&N cone filter

That thing ran nice and like hell!! All of this was done by using the stock cam. The speed density stock cams are very good. Don't be fooled.
