Guess the HP

Today. You can ask rat bastid he's the Dyno operator. My engine is giving the Dyno it's maiden voyage in it's new home so there's quite the learning curve and bugs to work out.
Let me turn the screws on that dyno. We will get 1200 horsepower out of a hydraulic cam 318. Lol
I was flowing a set of cnc’d AFR Chevy heads for him and he wasn’t happy at all with the flow numbers we were getting. I said what would you be happy with. Being a bit of a smart azz he said 380 and while I was bsing with him I changed the config number on my laptop. He was standing there but never noticed so I said let’s flow them again. This time we hit 384cfm and I said are you happier now. They will run the same but you have the best flowing AFR heads on earth. Lol

You’re in good hands.
Saw roughly the same as PRH posted about HP loss up top and moving the tq peak lower with hooker FW headers
It's the tube length. IIRC, they are in the 44-45inch range which is way too long for anything making some steam.
Had a different set of Hedman FW headers IIRC and they were much better than the hookers.

I've heard the hedmans are better in 2 ways, tire clearance being one of them.
Well, I think there's enough data out there to compare engines to get a believable number.
I'm 100% sure rat bastid isn't into making extra happy Dyno numbers....and like I said I'm really just trying to get the numbers to base my converter and rear gear choice.

You guys have made me curious. I know my fenderwells are 2"tube, but I don't know the length of tube or collector. Guess I'll have to grab a tape and check.....

The annular boosters might cause a little airflow restriction and cost a few up high but they are so nice everywhere else that they’re worth it.
Cool, thanks.

35hp gain from the dyno headers, peak to peak......... but almost 50hp@6800.
On that motor, with the dyno headers....... it was 13hp better with the adapter & 1050/4500 than a good ported 850 on a 1” spacer.
I also ran the 1050 on an M1/4500 with no spacer. That’s actually what went in the car....... it was basically the same as the M1 4150 w/the 4500 adapter.

Drum roll…where’s the numbers?!?!
Sorry guys I kinda jumped the gun, we thought we'd have this done yesterday. there are some gremlins still being worked out. Rpm switch needs replaced and won't be at rat bastids house till next Thursday.
I'll update asap.

Lol, yeah pretty shitty to have a dumb switch screw everything up.

Not going to be any inflated numbers with this deal, our personal engines (as well as some others) will be at the track so it will be figured out quick this coming season. Also we plan on doing mostly mopar stuff including intake comparisons, heads etc. and the results will be available on our channel but more on that later. FIRST we got to replace our new but faulty rpm sensor and make some pulls.
