What a beautiful motor Rick.

Love the valve covers.

Let me know if you need an extra pair of hands when it comes time to put it in the car.

I am serious. I know it's got AFR 195's, but I don't remember if they are competition port, or street port. I also don't have any idea what the cam is.

So, what heads and cam are you using?

What the ETA on install? Before 2010?

I'm trying to decide right now if I need to run them (as I'm only running 3/8 studs and I'm sure yours are 7/16).

It has the AFR 195 Comp port heads. The cam is a Comp 236/242 around .600 lift with a 113 lobe sep. No stud girdle

Right now I'm going to be running 3/8 stud. Brand new studs already in the heads and already have a new set of rocker arms. But I'm only going to be seeing about 5500RPM . Cam is a 268xfi 218I 224E .570 I .565 E lift with fairly aggressive ramp.

I think it'll go 125 on a decent track.

Should be a blast to drive.

I hate to admit it, but I'm pretty jealous. Do us all a favor and get that thing on the road!

Josh is right, you need to yank the 350 and get the show on the road! Maybe I will have to fly up there and tune it.

You said before it wouldn't go 125. Why the change in opinion?

I don't remember saying that it wouldn't go 125, but I bust your dumbass so often than it's not inconceivable that I forgot about that particular comment.

In all honesty, I think it will go 125. Regardless of what I may have said in the past, jokes aside, it should go that fast. Assuming you can half *** drive it, assuming that it doesn't **** out the 4+3 the first time you go WOT, and assuming you find a decent track; there's no reason 125 isn't attainable.

Damn, that's a lot of assuming. Maybe that is why I said it wouldn't go 125?

Under the table??? Don't you mean on the table?


Cars that have left power on the table usually end up leaving their dyno results on the table and wouldn't dare post a 1/4 mile time or MPH.
