Don't be afraid to make an offer on these.

Does anyone have any questions about these?
Is the price too high?
No body wants to run a 406ci LT1?
I am going to have to post these up on ebay; but would like to know more about why there is so little interest for them.

Thank You!

Dang can almost use 6" rods with a 3.75" stroke. Any idea what compression this would work out to with a 3.48" stroke crank 7 stock LT1 heads?

Here are a few combos to consider. I took the 7 stock heads to mean 57cc.

With 57cc heads, 9.015" deck height (9.025"-.010"clean up mill), 3.48" stroke, 6.25" rods, .049"thick gasket the comp ratio is 9.19:1. With no deck mill it is 9:1 even. R/S ratio is 1.8:1 If you meant 67cc the c/r would go down to 8.36:1


With 57cc heads, 9.015" deck height (9.025"-.010"clean up mill), 3.75" stroke, 6.125" rods,.049"thick gasket the comp ratio is 10.04:1. R/S ratio is 1.63:1 c/r 9.1:1 with 67cc heads.

One last combo would be a set of AFR 227cc heads with a 65cc chamber. .015" deck height (9.025"-.010"clean up mill), 4" stroke, 6" rods,.049"thick gasket. The comp ratio for this combo is 9.82:1

Thank you for asking
