I just purchased the 1262 lower intake gaskets because the 185's have the huge intake ports. I should have asked this yesterday. The 1250's look a bit too small. I need to know what people are using before I take the 1262's out of the wrapper.
I think they were 6.300 or 6.350....not sure. It was a basic rebuild 310 (0.050 over). I picked up an older 88 HO block for 30 bucks (the guy didn't know what he had), and now that I'm back at school, took it down to the machine shop and screwed around with it. A friend of my cousin needed a new motor and was interested in learning how to build a basic engine so I told him I'd go along with it.Grn92LX said:Thanks Joe. Do you recall what size pushrods you used with the 185's? What was the combo?
Christ Mike...that thing should scream. I'm guessing it's going to be shifted a lot higher than 6500 though. Probably 7000.Grn92LX said:Yah I believe you are correct, Joe. 1262 it is
Joes95GT, i'm hoping to see 340-350rwhp with my friends 306. I have no clue on compression. I think its a speed pro or a trw piston. It should run well with the AFM N61 cam (228/236 .544/.568 ) I expect around a 6,500 rpm shift. I wish my friend had a probe piston.
Do you know how to tell a stock style pushrod from a hardened? I need to know if he has to buy new pushrods instead of the ones that are in the engine now. (He bought the engine from his friend and I have no clue if the pushrods are hardened or not)
