So I got the engine back and look what I have discovered.... they had trouble installing their headers and covered 30-40% of exhaust port . No wonder engine had hard time pushing all that air out at high rpm
I just did Dyno Simulation and wow i think its that cam that loses all the power at 4700 RPM....
Looking at the simulation is almost identical to the real thing except my power drop happens much faster after 4700 RPM. Regardless not sure if i should be buying another cam or just keep it the way...
Good call on the cam. I did not think about that. I'll run that info by the machine shop to see what they say.
What cam did you end up choosing? I will also be running efi with this engine. I got fitech running on my old one really well. So I spoke to speedmaster techs and they agreed with my...
You probably did not see my question from the previous post where I asked if I could use 3v CHI manifold with speedmaster heads.
So No, I do not want to buy manifold from the same company but will do if I cant use any other 3v intake that will fit those heads.
i'll just go with high-rise...
Don, I have no doubt that If I can figure out what the restriction/issue is this engine will make over 500 HP. I am already happy with the torque numbers

Hey, no hard feelings here. I knew what I was getting into. It was simple decision to save money. CHI heads are about 2400 dollars while these heads cost me 1000 and that is with all updated valve train components.
This is not going to be racing engine and it will not see lots of action past...
The engine builder did all the work. I assume he knows what he is doing. they build mostly big blocks and race engine but definitely very knowledgeable
BTW, oil pressure stayed around 77 PSI the whole run. We did more then 10 in total. each time we changed something to see if the issue goes...
OK guys,
so after almost one year the engine was built and dynoed today. However, we have an issue....
So as i said, i went with the 408 cleveland stroker kit and speedmaster 220cc 3v aluminum heads. All internals (valve train) that came with the heads have been replaced with quality parts...
Thanks so much for looking into this for me. I already have Quarter panels so I do not need those however still looking for those corner quarter panels.
If you come across pair of those just let me know
