Re: 305 ET's
i dont have the slip in front of me but i want to say it was a 1.71, i just remember it almost being a 1.6xx with a bog off the line, that was with my 650dp now i have a 625 road demon and the car feels much stronger except the delay with the secondaires, so i just have to leave it on the floor when i shift it oh well

Re: 305 ET's
i went to a scholarship drags almost 2 years ago and they were only running 1/8 miles, and would only print 1/8 mile times. but my 86' iroc 305tpi went a 9.6 as its fastest. and slowest was a 9.7 it was very consistant. the only mods were slp cold air, jet air foil, hooker comp headers, flowmaster, hypertech thermomaster chip(junk),solid rebuilt tranny w/(shift kit, corvette servo, beast sunshell) and weld circle light rims with worn out passenger tires lol. id like to see wut it runs with a couple more mods i have now
