I went with the Mamo 220's and a mid 220 cam. Just waiting on a really heavy box to show up in the mail. I'm pretty sure it will perform worlds better than the prc 5.3's and 228r I had.

I'll probably make a post once the rx is back together. Just a short block n ow.

Unfortunately not the same dyno. I moved to the opposite side of the planet. :-( Hawaii to Holland.

I do have the SAE graph though...bout as good as I can do.

I still have to find a dyno....

The only other change will be, I had a fast 102/102 before and will have a fast 92/holley 90mm tb this time. All else will be equal minus locale. Dropped the 102tb as at 420rwhp anything above 70% tps had little to no effect on manifold pressure. And dropped the fast 102 for logistical reasons. Want to run a strut bar again. The 92 will be ported so pretty darn close to a stock 102 if not a tad better.
