So using your suggested 1.25 correction factor that would be [email protected] and [email protected], which would probably be higher if he had given it more RPM, still respectable numbers and probably closer to what I was expecting. Does that sound about right? In your opinion, since hp is still on the rise @5000 what would you guess the peak would be?At 7,000 feet I think the general correction factor is about 125%. I think my 540 becomes a 454 (80% - 1/1.25) if I lived in Santa Fe which is at 7,000 feet. I think at 7,000 the borameter is like 25 inches versus like 29.2 for SAE at 77 degrees. So the temp is close on dyno here. The 1.63 or 61% (1/1.63) would mean the dyno was at like 15,000 feet (borameter is like 19 inches vs 29.3 sae).
I've been doing a little reading on the interwebs and there are several calculators for figuring CF. Would the extremely dry air increase the CF more than 1.25, say, between 1.3 and 1.4? I'm not buying the 1.63 CF either, I always thought the numbers sounded a little high for this combination.That about right and you probably would be over 500 hp (say 510 hp) if they took it to 5,500 rpm. It was still climbing at 5,000 at about 5-6 hp per 100 rpm. I think that is about right given the modifications you have and still is better than what people were expecting. Based on your cam, which is an LS6 cam (239/246 at .050, .540 lift on a 112), similar compression, little bigger motor, with some worked over heads and a better manifold it is about in line with what you have. It may have even carried to 5,700 rpm making it a little higher. Its going to be a nice street driving engine with lots of tq and some nice top end.
Thanks. I've got a new set of stock pulleys if the four core radiator, shroud and seven blade clutch fan don't do the job. I'm hoping it works out as the smaller pulley means less parasitic loss and less chance of throwing the alternator belt at high RPM.Motor looks great. Love the graphics and the header look nice. On the small harmonic balancer pulley keep on eye on that as now with all this power it will generate heat and you may need to go to a bigger pulley to get water pump and fan up to speed for idle / traffic situations.
Actually I had the intake done first and was going to use black finned aluminum VCs but the manifold looked so good I bought a set of tall stock looking VCs and dipped them too. I think it worked out pretty well.I just noticed the intake has the same hydrografics as the VC very cool
Nice!Dozer, I sort of hardlined the filter inline with a steel line from the f pump. I'm not trying to show off here but.....I do prefer a proper steel inline filter than sintered bronze, even tho the install has a "Ford" appearance.

PS, I;ll check my dyno sheet but it seems the beast only made 424 HP at 7000' in CO Springs. Corrected to 603. Forgot the baro on that.
Also, Dozer Mark's enigine also had ts peak TQ aT 43-4400 rpms. Peak HP was at 6100.
OK yours looks cooler!
PSS I finally stuck a 6300 rpm pill in mine, as I was starting to have WAY too much fun. AS will you!
