Thanks guys, thats all good info. I know its hard without having all the info to go on. I'm guessing the heads have had some work done of some kind based on what y'all are saying because the cam in the car is definitely a larger cam than the ram air iv and the motor doesn't seem to have any problem pulling up to 5,000. Since it runs well on 93 I'm guessing the cam is big enough to bleed off some cylinder pressure and is whats allowing it to run on pump gas. I've put a little over 15,000 miles on the car so far and haven't run into any issues yet but I know of course that doesn't mean I won't have an issue tomorrow haha. The guy I got it from seems to have made the mistake of going to a shop and just telling them to build him a motor without telling them what he wanted to use the car for and thats part of the reason he sold it. The rest of the drivetrain is not matched to this motor at all. I'm thinking that once I get some 3.42s and the 4 speed I have waiting to go in it I'll have a better idea about how well this motor combo can perform.
So a follow up question, assuming these heads were modified to work on this motor am I leaving a ton of power on the table running them, in relation to other iron heads of course?
