I'm fixin to do a half fill on my virgin DOVE-A 2 bolt block, its boss bulkhead, Ive got a set of procomp splayed 4 bolt caps, question is, what ARP studs will work for this setup? This will be my backup motor for my 68 cougar bracket car. should be around 950hp when its done. 4.500 stroke, h beam rod deal with a 4340 crank.

Looks like ARP only lists two 4 Bolt Kits, one is for a Windage Tray.

Page 80 and 81 in the catalog.

Do you have the OEM main bolts? Why not use them and some similar fasteners in 7/16-14 for the outer bolts of 2, 3, 4?

installaing the 4 bolt caps is a lot of work and $$$$.you have to fit the caps,and have it line bored etc.by the time your done it would cost more than $1000 for the caps installed.i think as a back engine i would leave it 2 bolt as it is.the dove a block also has a short cylinder for a 4.500 stroke.maybe ok with a 6.800 rod.
