BLEW THE DIFF

[Scorpma82]

A 500 Holley?!?!?!?!

Isn't that a bit big????

[leigh7005]

NOPE IT LOVES IT

[leigh7005]

i want to go 4 barrel but need a manifold.it was goin to be a blow through turbo but ran out of time so i jets jeted the carby and it runs like a dream pulls away from 6s and v8

[Scorpma82]

Ur best chance of a 4 barrel astron manifold is to remove the original plate for the 2 barrel and fabricate a 4 barrel version

[leigh7005]

havent been on for ages sigma now has a 302 windsor and 5 speed t5
