do you think it will run a 6.7 in the 1/8? here's the deal. a friend/customer wanted me to do a street pump gas motor for his 4000lb. 73rr that he could cruise anywhere, be very low maint., and take it to the track on sat. so we chose a 505 with stealth heads, not cut-87cc. a 242/246 hyd. flat tappet cam. i put a victor intake and an 850dp on it. AFTER the plan was made he decides to put it in a back half scamp with too much gear 4.89's. also it will be a true footbrake car with a GLIDE. i figure it won't want to turn more that 5500? think it will run close to 6.70?

Close, I run a pump gas 505 about the same 4.56 gear, stick shifted , runs 6.50 in the 1/8th but I shift at 6800  
it's ok to butt heads, just don't do it with a butthead

Whats the scamp weigh? Converter stall? 6.70's might be pushing it. The camshaft is leaving alot on the table.
11.48 @ 120 with a 1.80 60' 318, stock 1.88 heads, stock 904, Pump Gas, 13 lbs of boost.
9.94 @ 134, 318 on pump gas, 14 lbs w/ Eddies, transbrake 727, 3600 lbs, 3.54 gear and 28's.

he's talking about a 4000lb B-Body, don't think 575hp will get it to 6.70s
