Yea i think so.
They have DOHC just like mine.
They were based on the LT4 head cfm flow and basic design but are DOHC
What do you think I got the heads off of?
DOHC heads dont make more HP as Pushrod 2 valves
But, they do make more usable torque throughout the power band especially around high rpms.
So anything else?
And yea the 78mm is a bit small but it was the biggest i could order based on the LT5's upper and lower intake beacause the intake ports on the head are unlike any other SBC.
:banjo playing: Why am I hearing banjos?
OK... you lost me again Roscoe... So now you have LT5 heads on an LT4 383 pushrod engine? Can you explain how you managed to retrofit DOHC LT5 heads to the 383 LT4? I must be going nuts here, but I cant seem to find anything on the internet that supports what you just said. Unless you want to recant your story and say that you have a ZR-1 LT5 swapped on your vette, that would be a bit more credible... Educate me/us please?
I just verified with an ASE Master Tech on the validity of your claim... I basically asked him if he could build me a 383 stroker LT4 with DOHC heads out of an LT5 and per the corvette manual and his expertise, its IMPOSSIBLE to perform. BTW, I cant seem to find anything on the net about a DOHC LT4 engine. Ball's on your court now bud... we are waiting.
