I have a chance to get a a4 block virgin bore so its a 328 stroker

Virgin bore A4 block (328 ci)

Cola crank (two key ways)

Eagle rods

Probe pistions

roll master timming chain

moroso 7 qrt pan

Melling high volume oil pump

Crower severe duty soild lifters

Rolmac balancer

stock ford timing chain cover

SFI flex plate


I do not know a lot about the a4 block is it strong like the R302 that replaced it? also is it a Siamese bore or non siamese bore? what are the power limits on this block? Also this is what the guy said about the rotating assembly

Its a Cola steel crank 3.25. The rods are Eagle H-beams. I forget the details of the pistons but know they are low compression around 9.0:1 depending on the heads cc's. Will this be good to around 900 hp?

any help on this will be very appreciated the faster the better

 

Pm the person you have a question for, thank you

 

Just did that sorry about that just trying to see if anyone else knew anything about a4 blocks

 

that's fine just let me correct the thread title so it's in agreement with forum rules

 

A4 non siamese, will handle 900hp, R302 a bit stronger and the R302 certainly has the ability to go 4.125. All in all, on paper from what you wrote, its quality stuff
