I have a 4l60e built by Lonnie at extreme automatics. Takes 700lbft of torque launches just fine so far and shifts great. I was thinking about having him build me a th400 frmvb for my new no prep adventures. Don't see him used too often here.
Final numbers, 830hp and 672tq. Yeehaw!!! Eric Roycroft delivered! Its a beast. Its sat, ima let him get packed up n back home with his family before I get all the details.
Lol, I have a feeling Smokey knew b4 me...perhaps he is ERs alter ego messing with all of us on these forums!?!? Eric emphatically denies it, lol. Eh, nothing wrong with alil flattery these days. Im extremely thankful Eric and this build have delivered! It s gunna be a real handful.
P.s. I think my tuner may or may not have started thinking about drinking knowing whats coming his way, lol.
Its a big cam, custom specc'd, Eric doesnt want the specs shared, I must respect his wishes there. I ve seen some similiar sized cams on this forum before.
Man that’s a bad *** build
what fuel are you running on the dyno?
and what going on with that dyno the numbers are jumping all over the place?
93 oct, pumpgas. It looks like there wasnt any smoothing applied. Not sure if its from the dyno itself or what honestly. Fuel consumption in the Holley Dominator showing 412lbs per hour which is on par for >800hp. Im hoping Eric can get a graph printed and smoothed.
i was quesrtioning the use of hydraulic roller myself but seems to be working out just fine lol. congrats
time will tell, im not easy on my hotrods. I will drive it like I stole it...often. I ll be makn some passes at Atco eventually. Gotta drag my buddy in his 557" bbf Ford f100.
Cool combo, nice peak numbers, but I have never seen dyno numbers so inconsistent. 44HP jump from 6500 to 6600 RPM? Torque peaks, then drops, then rises towards peak again, something is amiss... 1.85HP per cube and almost 1.5ft lbs per cube are solid numbers.
