BTW: a customer did a cam swap and tune up (jetting, carb rebuild) on a BBC that needed a better idle, so you would think with that the car would loose ET and MPH in the 1/4, nope he picked up .3 and 4mph in the 1/4. Not bad for going to a smaller camshaft. ;-)

I got a dynoed best right around 380HP. I thought I should be making much more than that, thus this latest excursion. It did allow me to find out that my heads were not flowing what they were supposed to be though!

The 224/236 is not a bad cam, you could tweak that one some and put the right parts with it and find power, but if you could handle more cam it there is more in it.

When I went to the 396 I had MTI do a little work on the CNC heads I had and I made right around 400rwhp. I always thought I'd left a bit of power on the table by not going to bigger valves(I had 2.0I, 1.57E). I had a chance to by a set of LT4 heads they had done w/ 2.08I,1.6E valves and a direct port under intake nitrous kit. the car they were on had a solid roller and ran 10.2@141. I had MTI prep the heads for a hydrolic cam, install, and tune the car. The heads were supposed to flow 300cfm. I never got a flow sheet (stupid I know), but I ended up right around 385rwhp. I believe the heads flow well, but I didn't know anything about matching them to the cam at the time. I figured more air, more power. I then got a street twin clutch and removed the weight from the flywheel (thought I needed to) wich made it out of balance. Now about 800 miles later I think I have a bearing going bad. When I get the bearings redone (once I'm sure that's the problem) I'm going to have the heads flown and match the cam to that. It's been pretty expensive and fairly diappointing so far. At this point I just want the car to run right, but if the motor has to come apart I'd like to get the power I think it's capable of.

I understand your position. However, I haven't heard any numbers (I don't need names) of anything except Matt's - His dyno and trap speeds don't seem to add, IMO - that's another thread tho.
I'm not trying to make a cheap shot at you; just anxious to see some numbers from your combos.
I'm not doing anything crazy or going fast, so my opinion counts for squat.

This guy cracks me up....
Makes a ID just to bad mouth me, I must really get your goat to be that much of a sally that you can't say it in person or by using your real name.
Your only other posts were on this thread http://web.camaross.com/forums/showt...94#post1888194
So that shows your MO as someone just to bad mouth me.
Grow up, or have enough sack to show yourself. That's what you have to love about the internet, anonymity gives spineless punks like you a back bone.
On top of that if you just read a few posts above that:
"BTW: a customer did a cam swap and tune up (jetting, carb rebuild) on a BBC that needed a better idle, so you would think with that the car would loose ET and MPH in the 1/4, nope he picked up .3 and 4mph in the 1/4. Not bad for going to a smaller camshaft. ;-)"
With Matt's car it gets me too because that thing was one hell of a low budget motor and the cam was ment to make power at a low RPM (6000rpm), I've driven the car at the strip and it's goes well until a mis develops at the high end and still traps the same speed. There are some tuing issues and other things going on there with that thing but I'm pretty sure we will get them worked out and tweak that thing a little bit more. There are some bugs to be worked out definately but for now a 100+gain from his new motor and well over a second reduction in ET is a good place to start.
Why do I have to repeat myself for a spinless hump like you?
Anyways, at least I get the pleasure to know that I must really bother you enough to make a false name and go on doing this crap. That's all just too funny.
