to beat a GM 602 crate

i grew up at the race track with my grandpa, he ran allied and ump modifieds since the dawn of the dirt modified, then raced 360 sprints his last couple years. i have always been around racing but I'm hoping to put the old modified back together or grab a used one next year hopefully if my palace chase the the air national guard goes thru to race in 2016 most likely.
theres a picture of his car back in the 90's. he passed away a few years back. i wish i would of gotten to learn more of his mopar engine recipes growing up
