I've always been told that every 50 cubic inches needs roughly 7 degrees more duration. This proves that cubic inches does in fact tame the lopey idle.

Yes sir, if I had that cam in a little 283, it would sound like, well.....a 283 with a HUGE CAM in it. It would be much more "rowdy" sounding in a smaller CID motor. Thanks for the comment! We are taking the SBC 400 Z28 to the track TOMORROW for Test N Tune. I'll report back on how that car does. It's best ET with my 770 Holley and an Accel Distributor on that motor/car was a 13.4 but my son has Holleys Sniper EFI on it now and we are "expecting" to see some gains. Thanks for watching! Pops

No replacement, for displacement! I dont understand why people overlook the 400, and instead opt for the 383... If built properly, the 400 is a better combination!

Sure the one on the stand revs quicker it's not connected to a 40/50 lbs tourq converter

I bet a clutch or TC weighs more than that. It's the same thing that I told my son when he was listening to this video. The 350 isn't a high compression motor, just dished 350 pistons with 64cc 1970 Corvette heads and UNLOADED (not on a Dyno) so it's definitely going to rev super snappy. It's just a breakin stand (but boy I wish I could afford a Dyno room!) 😂 The 400 is a dished piston engine also. She runs real good in that heavy car (3650 lb).

I'm about a year away from a law settlement for my hips . And that's what I plan on trying to make a business out of but I want a Mobile DYNO I saw one on a video where the black diesel explodes . I'll take it around to all the car shows and hoe many people would love to dyno their car at those meets

Sounds pretty dang good. Sure hits 5krpm mighty quick. I'm scared of Comp Cams, everything I see suggests 80% chance of scorched lifters.

Everyone and their mother has been using Comp Cams since the stone age.... they're as good as it gets.

@@PotatoeJoe69 You haven't heard of all the cam/lifter failures? I used to think nothing of swaping cams but since all these reports I stopped doing that.

The issue is the MOTOR OIL used during Break In fellows. Also, if you can, like I did, have your camshaft NITRIDED for an additional $150 from Comp. That, along with a good break in oil with a GOOD AMOUNT of ZZDP (and/or the addition of ZZDP Additive like Rislone makes and I use) will get the cam broken in without issues. Modern engine oils have been stripped of Zink and Phosphorus that help "lube" and protect the cam lobe surfaces from premature wear during the critical first 15-20 minutes of running. Also, you must bring your engine up to at least 2000 rpm so that the lifters will spin and wear evenly. I have had a Comp Cam go flat once (it is about the only brand I use on SBC's). They replaced the cam and the lifters for me and that's when I started having them Nitrided and using additional ZZDP for the break in period. Pops

The lack of torque converter will make it rev up and return to idle quicker.
