360 Help
Hi Guy's,
I know a this question would have been asked before but all advice would be greatly appreciated.
Here is the low down I have a 360 in a 63 Valiant wagon with 727 & a 3.9 diff so far this is what I have & am about to attemped.
Motor 360 is +40 I have J heads which are getting large valves & porting, polishing & port matched. The bottom end is standard as are the conrods. I am looking at a set of KB 190 Hypo pistons hopping to get comp up to approx 10 to 1 maybe a little more is possible. It also has a set of roller rockers & I am running a Eddy Performance inlet with a 750 Holley vac sec.
Trans is 727 with 2500 stall stage 2 shift kit heavy duty cluches & bands
Rear is LSD 3.9:1
The big question is what cam do you recommend for the drag strip which can still be driven on the street...I am open to solid or hyraulic cams I am not after a ball tearer just something to have some fun with at the strip. last time out it ran a 15sec which I would like to get down to 13.
Thanks Graham.
Heres what i did with a 360 awhile back, it was the best SB i owned, super screamer, ran 13.2s in a fully dressed 73 Swinger, that was on the limiter in every gear at 3700ft. Alt. I'm sure you want to keep the 3.91s, but 4.56s ran great in mine.
71 360: .060"
stock rods, ARP bolts, polished crank, everything balanced.
KB190s (.040" quench dome) Final compression was 10.3.1 with .039" FPs
Stock prepped J heads with stock valves.
XE 284H: 507/510 lift., 240/246 dur. @ 50
Hooker comp. headers, RPM air-gap, 750dp.
MP dist., MSD 6AL, timing was 20* int., 36* total, all in by 2200 rpm.
2800 11" (needed more converter, but haveing the 4.56s helped alot)
904 trans, Cheetah RM VB.
8.3/4, 4.56
PS,PB car.
Ran great on pump premium.
The car had all steel, all glass, full int. (with bench seat), full bumpers, you name it, it was there. With me it weighed around 3500 lbs., car had easy 12.9s dialed in @ that Alt. That car was a blaaaaaast to drive!!
