weird BBC combo

[prairiehotrodder]

do aftermarket blocks come right at 9.8 deck height ?

Would this combo work ?

4.5" bore
3.76 stroke (factory 427)
6.7" rod length
= 478 cubic inches and with a 1.27" compression height piston the total would add up to 9.85 "

I'm just asking because i have the crank and pistons. the pistons are mahle with a 10cc dome. Depending on the deck clearance this would give around 9 - 9.5 CR.


If it was put into a tall deck block with a 7" rod it would add up to 10.15"

The last time I had new blocks in my hands was about 15 years ago and all four of the dart big blocks had to have the decks cut. Sorry but I do not remember how much. I would give dart a call.

USA Performance has some taller-than-stock blocks. Ask for Dave Bieneman 704 397 7979

[Orr89rocz]

Darts are suppose to come .005-.010” taller for proper machining finish

Molnar has rods at 6.635" and Eagle has 6.660"

thanks guys. Those 6.635" rods would put me at 9.785 according to my math. That would work good with a short deck block. I won't be building this combo but i'm trying to sell some parts and people have asked what they can build with them.
