292/508 question

Rigger
You don't need that 292 cam for a raspy idle, you need its tuff-guy overlap. You can put that on a lot smaller cam, and make far more streetable. I think they call them Thumpr's, or Whiplash
And if you put that 292 cam into an 8/1 engine, it won't sound nearly as tuff. That cam needs a lot of compression.
So then,after you boost the compression,you end up with a $4000plus engine,that gets 8mpg,has to burn premium grade fuel,that has a soggy bottom end, that needs a BIG TC and 4.10s,that you cannot parade at 2.5 mph...........and all just for the tuff-guy idle?

Well, you might need a Multi-strike CDI to keep it running, but you probably woulda needed that for the 292 anyway.

I got a cheaper idea;
crank the timing back on your stock engine, waaaay back; then jack up the float level, and fudge-up the mixture screws, and idle it down to just about stalling. There you go,Badaboom, free bad-azz idle. If you do this with a dial-back timing device, you can crank the timing back up when you leave the show,from the front seat, and get your engine back; I paid like $130 for mine, and it has built in signal amp that eliminates your ECU, and you can trigger it with anything, including points.
Lemmee figure this out; 4000 or more versus 130,hmmmmmmmmmmm.

Ok you got me; it won't sound exactly the same, but you can do that to your 276/284/104 cam, and it will, and it want's only 9.5 Scr to make a chitload of low-rpm torque, and will be reasonably happy with a TC in the 2500 to 2800 range and 3.55s, and best of all will idle down to 550 in gear,which will badazz bop along at 5mph, and with a bit of brake drag, I'll bet she'll parade at 3.5 to 4 just fine
Oh yeah, I almost forgot, point to point at anything over 2200rpm, I bet, if you're sharp, you can sneak up on 16/18mpgs. I bet you could get a lot-more with an overdrive. Like into the 20s,lol
But hey, if you gotta have a 292 to hit 112 in the qtr, well, sometimes you do what you gotta do.
