hi, i just got this stock 74 javelin 360v4 about 6 months ago. i'm having a 401 with indy heads and intake built. it's going to have 10.5 to 1, 560 lift cam, 3500 stall and a ford 9 inch with 3.70 gears and a 750 holley. should be done around may. i should be in the 12's but hope i get in the high 11's with slicks. i'll post time slips when the car is done. but i think i'll need a 4000 stall and 3.90 gears to get in the 11's. but you never know until you run it. a guy with all most the same setup but had ported iron stock heads and a 3000 stall and a 4.11 gear pull a best of 12.04 in same kind of car. but said car was a pig off the line. it need a 3500 min stall. friends told me 4000 stall would be best. but i wanted to keep stall down for the street.
it's going to be a street car that runs on pump gas. i kept the cam, rear gears and stall down because i want it very streetable. but if the setup doesn't work as well as i want i'll try 3.90 gears
