Here is the dyno sheet:

I am very happy, especially when you consider I am running unported Kaase P51 heads. I really believe this motor is capable of 980 if it had a larger carb, larger cam, and ported heads. I did go a little small on the cam due to me wanting a low maintenance engine (with regards to valve springs).

Now I need to take the car down to have custom headers made, get the right converter with the ATI Powerglide, and some other details (like a belly pan--since I do not want to run an engine diaper) etc. so the car will not see the track until January.

Here is the video!

Shooting for January. Still need to get the trans and converter and get the custom headers built--so it will be a couple more months.

That thing sounds sweet!! Cool Congrats on the #'s. Now, myself having never been in a dyno session, what is that high pitched whine/squeal when you shut it down, is that just the hub on the dyno?

2 carbs would need a tunnel ram...........the Weiand out of the box I'm not so sure it would have made much diff on his combo......besides I think the unported exhaust is whats gettin in the way right now.

Yeah I will be porting the heads, more carb, more cam next time around when I refresh the motor---one reason why I will be watching your build closely for sure.

What is interesting is the hp peak is at the same rpm as my 4.300 stroke 562. I would think this engine would have a lot more port velocity than mine and if the crutch is the exhaust port would it have peaked at a lower rpm ?

I know this is like comparing apples to oranges , but this engine's in /ex valve ratio is more equal than mine, the smaller carb does not seem to be having an effect on the peak rpm so I would guess something has to be happening to the incoming fuel mixture at this rpm on both engines.

Its got to be the intake tract or the exhaust tract and I am leaning more to the intake side myself.

Anyway the engine is making awesome power for what it is no doubt about it.
