Header/manifold dyno test
VERY Interesting post!
I don’t do magnums just cause I’m old school and have too many motors as it was when sb magnums came out. I’m not opposed to them I just never collected any.
This dyno test intrigues me.
I thought the 340hp’s would have shown more than the 318’s even with that mild cam magnum, I’m sure they do with other builds/combos, cam etc. but that was surprising.
The 318 vs. 360 logs also interesting that they were so similar in hp. I kinda thought the 318’s were little chokers even compared to the 360 larger ex innards but still logs.
I have headers ( won’t say the brand but they are but not the good ones ) on my street Scamp and I dislike them ( hot, stinky leakin, speed bump paint removin, gasket blowin, noisy…Ok enough of that ) but the car came with 3” collectors on full exhaust so I was bein cheap.. my bad.
24 years later I am looking at the manifolds on my shelf and realizing how young and foolish I was when I built the car.
Since I'm not looking for E.T.’s I will be putting cast manifolds back on the car. Hahaha, Yes the headers are still on the car! old and foolish now.
The post shared has helped solidify my decision to go back to manifolds and once again thanks to FABO members for spreading awareness.
This machine will soon be CO free again…whew is it dizzy in here!?
