340 to 416 stroker build need advice
ARP main studs is all you will need on the mains for most stroker applications. Like moper said if you need more you really need an aftermarket block. You will need to have the block line honed when switching to the main studs. And take your oil pump to the shop because it will need to be clearanced to run the studs.
I am running 10.3:1 compression on my Eddie headed small block stroker with a custom ground retrofit roller cam 236/242 @ 50 duration and 586/540 lift intake/exhaust. TTI step headers into 2 1/2" exhaust. Holley 750 DP carb.
I went with Stage 2 ported Edelbrocks from Shady Dell Speed milled to 62 cc combustion chambers. I had to upgrade the springs to match the cam and also had to upgrade to 10 degree retainers and locks. The stock Edelbrock retainers and locks are not real beefy parts.
Bottom end is Scat steel crank, Scat I-beam rods, and Keith Black 745 step dish pistons. ARP main studs.
My engine was built as a pump gas street engine with power band between 2,000 and 6,000 rpm. So far very impressed with the torque and top end power.
