Nice! Those mildly ported heads helped carry the mechanical cam a bit further than stock heads would by miles! I think the low amount of porting did a great job. How did it do under the posted test rpm? Is there an example around 3K done?
I know the small single plane doesn’t take so well that low.
Just wondering.
Look at the tq drop off point...If you were shifting that motor it would be earlier than the hp peak rpm , or feel wrung out with the tq dropoff. Also has an electric water pump on it freeing up that top end .
This is a great build and imo more like 445-455hp motor which is still very respectable. I'm sure if it had a hair more squeeze it would tolerate less timing and vice versa. 30 or 32 or 34 is not a surprise with a small block mopar.
I had forgot about this thread, might have already gave my observation. Still cool stuff.
