Well, all this time I thought I had a flat tappet block, being it's an 84. I was talking to the dude who I bought the car from (my neighbor), and he tells me six months later (today) that it is an early 90-something block. Yes! and No! It's cool that I have a roller block, but I had my cam all planned out as if it was a flat tappet block. I was gonna go with the XE268H, but now I can't. What cam should I go with? I would say E303... everyone loves and hates that cam. Comp XE cam? Which one? TFS 1? Crane? I will have a ~2500 stalland 60379 heads by the time I am ready to put in the cam. It's a daily driver that weighs 2954 lbs. Would like to see 12's. See sig for more mods.

I'm going to have a very similar combo to yours and I'm going with the TFS 1 cam.

post the casting no's off the block.it will tell yhe decade and the year and dat will be there to. casting date will be something like 5e17. the decade will be in big no's like D5AE. C5AE is 60; D5AE is 70's E5AE is 80's not sure for 90's blockthe day and date is 5 is exact year; e is is month; 17 is day. this will verify the block.the difference in the roller block is the lifter bore is extended to accomadate the long hyd roller lifter, you can still use the flat tappet in roller block. but no roller in non roller block without using reduce base circle cam.you could use same cam grind but in roller version.

or pull the lower intake and see if the top of the lifter holes are machined. if they are it's a roller block, if it's rough casting surface it's not

Did he say it was out of an early 90's something Mustang? or just an early 90's 302 block? Because not all 90's 302's are roller blocks.

the first letter is the decade, the first number is year, the second letter is type of vehicle, and the next letter is type equipment. So E7TE would be 1987 Truck engine. there are different ways to tell if its a roller block. If the distributor gear is machined then its a roller, or if you see an xxx or yyy in the lifter valley. Of course, you could obviously see roller lifters maybe, or like he said about the machined tops. Why dont you ask the guy what it came out of. I'm assuming its carbureted?
