RE: FE intakes
By Randy - 04/20/2003 3:39:39 PM; IP 152.163.189.100
There's definately something wrong in my motor package. Here's some specs and some dyno #'s. 428 block-.030 over, stock rods, forged pistons w/ 9.85:1, Edelbrock rpm heads w/ 2.19 in.-1.72ex. flowing 300cfm and 240cfm @ .700. Schnyder cam w/ .230 @ .50 both sides and .525 lift, hyd. flat tappet. Perf. rpm intake, holley 800 dbl. pump. FPA tri Y headers, 2 1/2 pipe into flowmasters. C-6 fully built, 2500 stall. 9" w/3.25 track loc. After running a best of 13.1 at 104, I took it to a dyno shop for a tune session and left with no answers. These are sad numbers and no one at the dyno shop or my motor shop can say why. Also these are the best #'s of the dyno session and it's with open headers. H.p. is 262 at 4891 rpm, tq. is 472 at 3127 rpm. Something is really wrong with that. The car was hooked up to a scope first, seems to be right. Timing is 36 and all in at 2500. We changed carbs to a holley 950hp and showed a gain of 4 hp. Anyones best guess is it just does'nt seem to be breathing good enough, as for me , I'm stumped on the 262 hp at 4900 rpm. It would be a good motor for hauling a trailer load of cattle. MSD 6al and duraspark dist. Any ideas?
