i think we figured this one out tonight at the track, and 2.2 60 ft. times were the result. we were told by another banger with a c-4 that we were brake torquing it way too much(2-2500). the guy said that an old car like ours stands up taller when you torque it up not letting the weight transfer quickly. he said launch it at 1200 and it worked! picked up a solid .2! also we had the timing about 3 degrees too advanced, dale said the car was pinging top end. remember how i said we had 66 small chamber heads that were shaved but ran with 12 degrees initial because thats what the called for in the 271 hi-po car.....the car ran .3 quicker and picked up about 4 mph. now we got 9.3@76mph in the 1/8. not bad for a worn bottom end dished/cast piston 302. hes getting this through a stock single points type ignition, 2" glasspacks, and a very sorry stock c-4. now i think with the 2.25 flows, pertronix ignition, 3000 tci stall, shift kit, slap shifter he's solid in the 8's. thats only like $500! well if he can get the shifter from my neighbor and we do all the work ourselves. oh, to answer the question about the heads, yes the 289 heads have the same port size as even the "good" early model 351 heads. and the 289 heads have smaller chambers too without the smog bumps. the 351 does however have bigger valves but all you have to do is put the in the 289 heads. the 1966 and earlier heads are the best. i know it sounds wrong, trust me, we shopped around. also the hi-po 289 head isnt all that impressive either. the only difference is the hi-po has spring pockets and screw-in studs.....big deal. flow no better. hate to go on here but i ran tonight also and posted 8.41 @ 83 WITH A MUCH IMPROVED 60 FT. OF 1.86. there was a 2000 viper gts there also, he ran 8.34! only .07 quicker! i feel better than shirley temple on the good ship lolipop, timeslip already posted on the fridge! now have to change my sig.
