Figured I'd jump start this thread - any progress on the build? I'd love to hear how it turns out.
I am just about to tear into my 548, for a rebuild with a top end from Bob - AFR 325's and 680-700hp at 5,800-5,900. Once I got over the budget woes of dumping more $$ into a 35 year old boat, I decided to tunnel ram it as well - plenty of room with my hatch scoop.
4-5 years ago I set up my 64 Vette with one, and after a nice little learning curve, got it dialed right in. It's only a little 355ci (also with AFR's), so I stayed small on the tunnel (plenum and runners), and changed almost everything in a pair of little 450's, and it runs like a raped ape - Power everywhere, pulls hard from 3,500 to 7,000 rpm, and with crisp neck snapping throttle response - everyone assumes it's a big block when they see/hear it run. So now I'm friggen hooked on TR's - they flat out work!
Carbs will be custom 750's (flow like 850's), and I think I have settled on the Edelbrock Victor Ram 2-R. I'm a little worried the runner openings might be a hair large at the plenum, as well as the plenum itself being large as well, but I like the look of it better than the only real smaller choice - the Weiand Hi-Ram (1985) - plus I figured the eddy is a newer design with more taper to the runners, so maybe it will be ok? What kills me is I have a tall deck, and will have to run spacers (the block rails are already drilled for pinning them in) - all the new tall deck tunnels, like profiler, eddy, or dart, are huge inside, with huge runners, and are really meant for cubes larger than mine and spinning more rpm - naturally Wilson says they can cook me up one to work, but that price really hurts .
This build is a tried and true Bob M combo, except I will be adding the TR, so it will be interesting to see how it turns out on a dyno.
