Camshaft from Chris Straub is ordered. Should be here in a week or so. Getting close to completion for this engine. I'm excited.

Ok, so how close were you to begin with? I know you had some cams in mind, but were you way off?
I suppose the tricky part was dealing with those giant heads?

I was looking at two camshaft from howards first one was a
634/640 lift
237/243@ 50
110 LSA

2nd one was a
640/640
243/249 @50
110 LSA

Not sure on exact numbers just yet from Chris but in the neighborhood of:
650/620
234/242@50
108 LSA

I think I was kinda in the right frame of mind. But I'll know exact numbers when I unwrap it.

The big stuff is mostly done. I got an Eagle 496 Rotating assembly, Forged Crank, H Beam Rod, & Probe Forged Pistons, The Pro-Comp Heads have been completely gutted, all that is pro-comp now is the casting. Howards springs, retainers, severe duty stainless valves, comp locks, comp valve seals, new bronze guides, etc.

Still need to get pushrods, (Well those are coming from Chris too) just need to get exact length, fuel pump pushrod, distributor (got my eye on the MSD 8365), Gaskets (Head, Intake, Exhuast, Oil Pan, Timing etc)Timing Chain & Gear. I think if Chris carries all this stuff, I'll just get everything from him instead of jumping all around different places. Think thats about it. Chris suggest I run a Victor Jr intake manifold. Currently I have a Air Gap, I may do it, if I can sell my Air Gap.

Mariano that's the cam Chris made for our Monte, it took 6 tenths off the 1/4 mile et (12.20's to 11.60's) on the first pass, there's more there if my wife would let me play with it....you should like it.... wink

Hey Dave.....not to hijack this thread, but what was the cam specs on the previous cam you replaced. Damn......6 tenths on a cam change is HUGE

hey Greg, I tried one of the Thumpr's when they first came out, full roller.....227/241....547/530 on a 107

the cam Chris did for the Monte is based on the one he did for the Velle with just slightly less intake duration, 234 vs 238 in the Velle...the trick with Chris' cams is in the timing events (lobe and ramp design, something he doesn't put out there too much as you can imagine). People are amazed at how the Velle runs with such a small hyd cam, it's all in the combo which Chris is a master at. The lift in both cams is 650/629 and both of mine are 107's.....

I think the lift had a lot to do with it too, allowing the motor to finally breathe a bit....

If you are going to run a Victor if I may I'd suggest the 454R(O) if you are going to do any street driving. Are you going to use a 4150 style carb with an adapter, or are you going to switch to a dominator style carb? If you are looking to possibly go the dominator route AED has an awesome carb they call their Pro-Street Dominator. Check it out. It is as deadly on the track as any 1050 carb, but is just as much at home cruising the streets. I have had one for five years and have never had one issue. AED hand builds a carb just for your application.

Cam specs will be 643/612, 234/243 @50 108 Lobe Seperation. I'm gonna have to reteach myself how to drive the car now. That and I hear this motor will probably be knocking on 600HP & Torque's door. What kinda sucks now is, the New Stage 2 Bowtie 2004r trans I have says its good to 450-500 HP/ 400-450 Torque.

Drag racing with slicks is going to be out for awhile. I could send it back. For an additional $800.00 to make it a stage 3. What really sucks is it's $300.00 to make it stronger. and $500.00 to get it shipped there and back home.
