About

I found this car while heading to Van Nuys blvd.cruise night with a friend in 1980. I had recently destroyed my datsun Z up on Mulholland Dr. while racing Robert Caradine(kung fus'younger bro) and had the insurance cash in the bank.We were in my friends 73 Z/28 and pulled up on this orange/black 73 Z28 ,and what do you do? Drag race maybe? Hell ya! At the next few lights we raced and each time got beat,but i noticed it had a for sale sign in the back window. we flagged the guy down haggled price,came to an agreement and two days later(monday) i went to the bank and came home with The Orange Pumkin.It turned out that even though the thing was fast it needed some repair and some freshening of both the M22 and the well worn but well built engine that had originally been built for a Saugus Speedway sportsman class car that did not get completed but with some minor changes was perfect for a really fast steet car

Specs

when I first got it it was .030 over LT-1 pistons ,cam, steel crank,pink rods polished like a mirror ,Edelbrock TM1 intake with a 800cfm DP Holley.headman 1 3/4in headers, Hays clutch,15 lb fly wheel,lakewood scatter shield,M22 trans,4.56 gears in the 10 bolt posi,and the part that made it all work.GM angle plug"turbo" cyl heads that were ported by AirFlowReasearch .I re rung & brgding it and drove that way for a year shifting 6500-7000 power shifts every chance i could and tore it down, went .060over(cont.in mods sec. below)

Factory Options

norwood built real Z/28 , NO air

Mods
