List all the modifications,gears trans&converter.How many miles,on the engine? Let's start with a solid foundation on knowledge.

Hah this could take a while

73 360 block bored .060 over
shot peened rods
arp main studs and head studs
comp solid cam 525 lift 294 duration
kb 10.5:1 pistons
edlebrock performer heads. 2.02 intake 1.60 exh
1.5:1 roller rockers
victor intake
650 holley double pumper
est compression ratio 11.5:1

727
raybestos blue plate clutches
full manual valvebody
2500 stall

and i am in the thought process of possibley switching to an air gap..i think it would work better for my application

3.23 gears right now in process of going to 4:10
i would have to guesstomate at about 1500-2000 miles on engine
