Perhaps someone is interested in a numbers matching HO motor for their car. I don't need the number since my car was originally a 350 and I'm looking for substantially more power than even this motor will offer. The work was done on the motor by Harbor Auto Restorations in Rockledge Florida. The valve spring seats were machined for the Comp. Cams springs to match the cam. The valve covers and intake are not in the deal I don't think. I need to see if Jim Butler thinks the intake will work with his combo. I'm looking to offset the cost of the Jim Butler Performance motor. I also have a proffesionally redone Rochester carb that can go with this motor and a clean set of original HO exhaust manifolds for this motor which would also be part of the sale. Is there enough qulality interest? Thats what I'm trying to gauge. I've spent alot of money on asssembly and figure rather than open it all back up and start changing things radically to get the 600+ HP I'm looking for I could sell it to someone who needs a high quality numbers matching 455 to complete their car. I'll post the numbers from the heads and block early next week when the shop can get them for me.
Long Block, Exhaust manifolds, and Rochester carb for sale.
