:Thanks for the good comments,I was running original Boss 429 heads,572 c.i.,A-96 block,4.625 bore,4.25 stroke. I have 15-1 compression,alcohol injection,I tried a 190 shot of nos with 116 race fuel for the enrichment on the spray,It worked well.I didn't want to push my luck running the old heads,so I bought a new set of Boss Hemi heads from C&C motorsports,pistons to make it a 605 c.i.,a 4.5 crank,New cam,Sheetmetal intake,I run Rons terminators.The old combination ran 7.70s with a 190 shot.The chassis is mid 80s ladder bar,2600 with driver,it's got a Bruno's with a three speed lenco,Mark Williams nine inch.
.Thanks Pat
