[77 TRASHCAN]

I have a set of virgin 17's. I measured one chamber on each head. Both were EXACTLY 83.5 cc's......
I've read here that the 2801 is a high lift version of the 068. I'd just use the old reliable 068, which ONLY needs stock spec springs (just make sure you use NEW springs).

Any cam with XE in it's part number is worth NOT using!!!

Get the block zero decked, or as close as possible.

I recently saw a 78 TA at a car show. 78's used a taller scoop than 77's. The car had a Performer intake. He had his hood initailly closed. The car was immaculate!!! BUT the scoop did not look correct to me (he bought the car recently, as is, his TA knowledge was zero...) I made no comments about the scoop...

An iron intake will perform GREATLY!!! Even a 77. 78. 79 iron EGR intake. 68-72's are always preferred, though...

Exactly, which rings??? I hope they are not plain iron rings...

Don't worry about a specific HP number. Do the right things, this TA will be a blast to drive!!!
