Did you ever run your car at the track?? I still have some tires you can use.....

That sounds like a 12.40 formula to me, Let us know how you do!

I know this is an old thread, but if that combo doesn't run 11s, then I'd be looking for a plug wire that fell off.

Hope the guy pops back in, I'm curious.

FWIIW my 10.2:1 450 w/ootb Eddys, 1.75 headers w/a 236@50 solid ran a best of 7.43 with a 1.62 60 ft. in the 8th with an 11 inch convertor.

I bet he ran at least the high 11's and should be mid low 11s.

11.88 at 114-115

I am thinking its full body and interior its pretty heavy for that 355 gear, and converter, 12 ohs , change to 4.30 and a good 8 inch converter 11.40's 117 mph. my

I Like this.... Moparts version of "PASSTIME"

I don't think its enough carb for the weight to do better than the 12.40 range.

Where's Brett Wagner when you need him?

I bet this combo is much faster than most think. Im guessing if this doesn't run 11.7s first time out id be looking for what is wrong with it. 11.5s easy. And a holley 750 is a great carb. Alot less to be gained by going bigger. Don't ask me how I know.

I think I've got a nice comparison.
My car is a '67 Belvedere, probably pretty close on weight.

10.4:1 505”. E'brock heads, 0.587/0.593 287/294 cam, M1 intake and 1050 Dominator. Mopar 175K converter (~2800RPM) and 3.55 rear end, and 8 year old firestone 205/70/14 street tires.

12.54 @ 114 w/ 1.932 60'

With converter, tires and gear, it should go nicely into the 11's.
