If you stay with a short deck block, then a 565cid (4.25" stroke x 4.600" piston with a 6.385" rod) engine would probably be about your limit for cubic inches.

He can spec/sell you the right cam for your application.

Re: Stroke Me!!!
With 345cc heads and if you are planning to keep the rpm around or under 6K, theh you need inches. I would consider a 4.375" stroke and either a 4.560 bore with OEM block or 4.600" with an after market. This would get you either a 572CID or a 582CID. Just had a customer with this 572 combo and OEM 990 heads make 680HP and 655#/ft of torque.

This is pretty much what I'm after. Quite impressive getting the horse from the 990 heads. As far as a roller cam any suggestions on lift, duration,centline etc ? Would like to keep it under 700 horse. The SM exhaust I ordered are good up to 700 I believe.

Re: Stroke Me!!!
Stan once the engine combination has been settled on and an rpm range to run in along with some flow numbers off of the heads then a camshaft can be decided on. You've got alot of runner volume there so if it were me I would go as large as possible for sake of throttle response. A good hyd roller with the Morel Marine lifters would be an excellent choice or for a little more power go a tight lash solid roller with the pressure fed Morels.

Re: Stroke Me!!!
1/4" stroke and 345cc heads will leave alot of tq on the table unless your going to turn 6500+, did a 4.56x4.25 with a set of 325 i hade and didnt like it. I believe 310 with 2.25 valve on 4.25 stroke is the ticket for < 6000rpm.
