Pivoting from 340 to 360
So, the '72 340 I bought for my '73 Satellite was torn down and found to have significant scoring in the bores due to it sitting around for years. Condensation took that puppy down.
So, my mechanic buddy has an LA 360 block and crank that's been sitting in an oiled bag since 2010. Bored .030 over; I imagine its a cast crank. Line bored, from what he recalls. He's going to examine the cylinders this weekend.
I'd like your opinions on this BUDGET build. Some parts are coming off the 340. Going in a heavy car ('73 SSP), cruiser, 904 with shift kit, 2,000 rpm stall converter, 3.55SG. 318/360 Performer intake, '69 HP exh manifolds, Summit 600cfm vacuum sec carb.
- Hughes cam, 220/224 duration at .050
- Domed hypereutectic pistons, looking for 10.0 CR or better. New rings.
- new oil pan, new main bearings. 360 harmonic balancer and flexplate for the 904
- reuse the accessories, timing chain, etc.
I may be forgetting something, but I don't think so. Keep in mind, its a budget build and I'm not going racing...but would like to smile when I put my foot into it.
Thanks.
