This engine has been a longgg time in the making.
Started off as just a set of NZ EQ heads just before they stopped making them.
Then some porting and a cam to match. Then pistons...and well, you know how it goes.
Brian worked with me every step of the way to help come up with a combination that fits the bill.
All things considered I actually think it might punch a little above it's weight in terms of having 9:1 compression and 18" of vacuum at idle.
I'm impressed it carries a pretty good RPM especially for a stroker. The dyno stops at 5700RPM but even there it doesn't seem to me like it's rolling over "hard".
The tunnel ram and ported heads helps a lot with the breathing, also .640"/.657" lift using 1.7 rockers.
Final corrected numbers 466HP @ 5700 RPM - 483TQ @ 4400 RPM.
The guys at IMM have done a lot of really top-notch work, I couldn't have asked for a better result.
They've also put a lot of goodies you don't "see" into this to make it live and work optimally under boost.
When the blower eventually makes it's way on there, We're hoping to see something in the range of a reliable 600HP and still be genuinely enjoyable to drive/park/reverse with a manual trans. It won't be a racecar, the plan is to drive the wheels off it.
