I just found out that the pistons I have will not work with my 4'' crank. They tested one of them and it sticks out about 1/2 out of the hole. When I bought the pistons I was planning on using the stock crank and I thought just simply buying a 4'' would make it a 402. WRONG So now I either have to dish out $650 bucks for a new set of pistons or use the stock crank. To make matters worse spent the money I had on the stage 3 heads. This project is turning out to be a PITA

 

it'll be worth it in the end

that sucks about the pistons

 

See if you can send the pistons back, if not sell them and get the right ones, dont ditch the 4" crank you will regret it.

 

Forged pistons for a stock crank should sell easily.

 

what type of pistons?

 

sell the pistons - shouldnt have any prob.
i came close to having a similar prob with my build.

 

Probe forged pistons with 16cc dish, 4'' bore, for use with STOCK CRANK and 6.125 rods. I'll take a few pics and see If I can get at least some of my money back. I paid $500. I'll probably end up keeping the 4'' crank and selling the stock one.

 

HMMMm.... Let me call richard tommorow and ask a few questions. You may have just delayed my engine build more YOU *******!!!!!
If you decide to come off of them.

Man you could always sell those heads and buy a set of stock ls6 heads or somethin. Or even a mildly ported set. Make get some money back that way.
