Skip knows his stuff, he's got great combos. Never worked with the guys out in virginia but I know sd performance does good work. Getting a crate engine for what you want is the way i would go. Way better bang for your buck and you know what your getting, no playing around trying to match parts.

A 4.5 inch stroke in a 400 blok with that amound of hp and torque is prone to falier!!! with what your planning to do!!!! 4,25 stroke is max! on a factory block if you whant durabitely .Again bearing speed wil be a issiuew it wil eat lots of them.
also CNC machined heads are overated, because a CNC mashine,s program is ONLY as GOOD as the porter that installed it!!!!!!.
the best head ported in Pontiac land out there Is ""Dave Wilcox"" Driver of the fastest pontiac in the world ""Dirty birt"" aka Drunken injun. he did the head work on the Tiger heads and with CVMS build the engine .
CVMS dont belive in CNC port jobs and have tested and upgraded some heads for people that came from SD performance AND KRE to a higher level.
they got and get more out of heads then that SD claimed was posible. every head set they port is CUSTOM tailer to what the custumour whants!! same gose for there engines. they dont like the ""crate engine CNC head"", one size fits al aproch!!
CVMS uses Wilcox ECSCLUSIF on al there head work.
some KRE alu heads claimend to have flowm 310cfm where actualy 285 afther testing on a difrend flow bensh . you have a pm!!.

I don't know enough about your rngine builder to say anything about him but I've been diong pontiacs for a while now and sd performance know their stuff as does kauffman and butler. As for "crate engines", I was refering to the fact that each company has their own cobinations that are tried and true that you can buy in a ready to go package. I also don't think that any good engine builder cnc ports heads and then just leaves them alone, they all go back through and make adjustments where needed. Everyone has their own opinions a bout what stock peices can take. I know someone personally that built his own stroked 455 that makes 700hp at the crank and runs a 150 shot on top of that on pump gas with absolutely no problems. hes been running it for 2 yrs now on the street and racing it and all he did to the block was fill it to the freeze plugs and use the mega brace. Go check performance years in the engine section and you will get first had opinions from guys that actually build their own stuff and have great reputations in the pontiac world and can set you straight. Oh ya, Spott's performance is another good pontiac guy.

Disregard the part about not knowing who cvms is. Wasn't clicking for some reason. They do some great stuff but I don't think any better than any of the others mentioned by me or the other people on here.
11-20-2009 #65Teh problem with building too much HP is just getting it to the ground especially on the street. My 455 even with sticky Nitto DOTS can't hook up.
11-20-2009 #66Sounds like your going more pro-street then pro-touring.
This is out of my area but Skip Fix hit on the head. My brother 600hp GTO just spins like hell even with the 9" slicks and is somewhere in the low 12 sec area. A FB will be a lot lighter then my brother 68 GTO convertible but I would think you would need full on tubbed out car and a transbreak to get into the 9s.Some times I'm fast sometimes I'm half-fast
11-22-2009 #67is this the only edelbrock victor they have for the 400? do they have one that has a little more to it?
