Dusted off the 466 that was siting in the shop for 5-6 years.
So, it's been awhile since I messed with my old BBF, but I bought another project truck and want to freshen her up and drop her in the new project truck. I built the engine about 6-7 years ago and she ran ok, but then I pulled her and she sat in the shop for the last 5+ years. Mud daubers and even a mouse made home inside (I had the intake pulled and the cover came off, at some point).
I got her up on the engine stand and broke her down and found one cylinder that had slight pitting and one KY hyper piston that had the skirt cracked.
I found my old posts and this was the data I had 6+ years ago. With this build I was hoping to have 375-400 hp.
Since I have pitting I am going to clean that up and will probably end up going from 30 over to 60 over. I estimate my old static compression ratio to be about 9.1-9.2:1.
Based on the specs below, which piston could I go with, that would work with my zero decked block and milled heads and give me better compression ratio? I’m hoping to get her up to about 9.5-9.6+
Also, what’s that tallest/best cam that I can go with, with stock valve train?
In short, since I have to go with new pistons, how can I get my old mild build up to 450+ hp, in the most cost effective way?
D1VE block decked .020, balanced, bored .030, stock stroke
KB hypereurtectic (sp?) -15cc pistons. Stick out of block about .002
D3VE heads decked .020, 3 angle valve job on stock valves, intake ports smoothed out, exh ported (by me), .039 thickness head gasket for about .037 quench clearance, stock rockers
~9.15:1 comp ratio
Performer RPM intake
SUM-3501 cam Advertised Duration 276/ 286, Lift .503/ .503 (good for stock valvetrain)
holley 750 dp carb
cheap hedman headers
2.5" exh with "wide open" mufflers
straight up timing set
recurved dizzy
