yo, i working on a 89 iroc, so far the car has hypertec chip, complete flowmaster exhaust, and some heavy duty aftermarket trans.

i would like to get a set of AFR or TrickFlow head and cam kit, im just not sure as to what else i need to make it work... there is a kit on summit says it fits 87 up heads,cam, roller rockers and all gaskets, what injectors and maf should i get. saw someone used 24s from a lt1? is that possible? is there a maf swap out there to? im really new to this gm stuff....... HELP!!!! LOL

 

First off welcome. Now, what size engine do you have? More than likely that kit is for a 350, 383, 400 etc. If thats the case it wont benefit a 305 to much as the compression will be low. What are the specs/company on the cam and heads? 24 lb injectors will more than likely do the trick unless the cam is pretty radicals and yes LT1 injectors fit, people also like the ford svo injectors. But you should really ditch the hypertech chip and have a chip custom burned especially if you plan on doing major mods like you said. As far as the maf the stock one will be just fine. They make aftermarket ones but come at a pretty hefty price, if it works leave it be. Also what kind of mileage is on your bottom end? If its over 50-60,000 you should really have it freshened up (rings, line hone, possibly an overbore etc) or you could create a blow-by problem with the new heads on an older block. Some more info is deffinatly needed.

 

350, its low mileage, and the bottom end isnt going to be touched until it dies of natural causes. I was told if u put just a bigger cam nothing else, the motor wont turn past 25-2800 rpm bc the maf doesnt read the increased flow?

so...the svo injectors..are they the same as regular mustang injectors w different flow rates? the p.i. headed mustangs have 24lbs in em....same injectors?

 

Putting a bigger cam in with MAF isnt a problem, thats why MAF is nice, it will recognize there is more air being pulled through and compensate in fuel. Of course a tune would bring out all the power potential. Now Speed Density wont compensate for anything and requires a tune for a bigger cam. As far as the injectors go I'm not to familiar with SVO's. I went with Accell injectors cause I found a good set cheap.
