Destroked 318

[SS Lancer]

Hello - thanks to all who have helped me figure this Gasser motor out over the last month or so.
Ok I just purchased a 3.20 Stroke NOS
Bob Glidden crank and its on the way to GA .
Im planning on a 60 overbore or 3.97
Bore and crank accepts standard LA rods which I have a box of new H Beams so im going to have custom pistons made unless someone can come up with a formula for me on this issue .
Still running 340 Rpm heads so I have the 60ths area in chambers I can have that milled out or use it to accommodate a dome piston after all I want atleast 11.5.1 compression or and even up to 13.1 compression if I can achieve it
Thanks Chris
PS yes weight per CI class Im running with.

If you are having custom pistons made you can have a dome put on the piston that fits the edelbrock head....

Most likely will do that .
Another member Mad Scientist guy came up with a proposal also to turn crank down to 2.100
6.300 Chebby rods and off the shelf Icon pistons with a 4" bore also.

sonic check going to 4" maybe also with .060
I never bore more than i have to- ring seal and all that
check your piston weights with the chevy piston / rod vs mopar piston/ rod
go lightest - with best ring pack i.e. no 1/16 ring chevy piston
tough to get compression with short stroke but you can do it
dbl check cam centerline to deck B-4 ordering pistions/ rods
cam will change with 6.125 vs 6.3 rod
