My HP was still climbing at 6500RPM on my 406ci. IF you have race ported heads then the heads should support 6500+ RPM no problem so your HP should still be climbing at and beyond 6000RPM to valve float, can't figure that out.
Also you vacuum is too low for some reason, I have a 242/248 duration and put 10-11" at idle.

So - this is somewhat in the range you guys are suggesting to ensure no detonation? The 6400 is nice - not that I wouldl visit that...but what concerns me is the memo on 500+ c.u. requirement and a 3500 converter

Thanks to all you that helped me on this, I learned quite a lot with this thread. I have a low mileage 355 with forged flat tops that I'm stealing off my kid. I am going to order the AFR 180 Competion heads, the Crane Pro Series shaft rockers & go with a solid roller. I was considering doing a complete engine build with a aftermaket 4 1/8" block, but using this engine I can afford to go to a 5 speed with a little more gear this year. I also ordered Comp Cams "Camquest 6" to banter around numbers. Now I need to figure out how many cc head I need to order so I can get this going, it's a 2-3 month wait on the heads! Thanks again!

I will back you up, five minutes or five miles whichever comes first Seriously though good move, those are the new design AFR heads ? If they are they flow good, that will be a killer motor
Also if you are looking at the Comp Cams lifters, make sure you get the new design with the roller oiling hole, lots if the old ones around at the jobbers and stores

Actually, I think I might get a kit off them, I have to do the arithmatic, they will grind it with the 4/7 swap. What "cc" head should I order? I was thinking 64, I thought this would be the right choice running a flat top piston 355 now & when I recover from $$$$$ this year, I think they will be OK for the 377 or 400 shortblock I build next year....what d'ya think??????

if your going to a 377/406 size motor now is the time toorder the new 195 eliminator head.

If the only purpose of solid roller is to rev to 7500 RPM then I have the wrong cam because I have only been there a few seconds out of hundreds of hours driving. The power band is supposed to start at 3000 RPM, that doesn't mean you have to cruise around at that RPM either, I have over 450 ft/lbs at 2000 RPM. Just because you can rev it to the moon dosen't mean you have to hold your foot to the floor backing out the driveway.
Most of my driving is done at 2000RPM, don''t forget if the solid roller cam makes more power at 6500RPM then it probably makes more power at 2000RPM. For me, personally, I see no reason not have a solid roller in my motor. I like keeping and eye on the valve train, adjusting the lash etc. it is my hobby, if it was a DD and I had to drive it to work I would put a flat tappet cam in it

After building the most radical 502 then 572 blown motors and a blown pantera 351w... and i've had more cam changes than ex wives (a lot..lol).... i've only done either hydro roller or solid roller....never had standard lifter engine...
BUT...i can tell you... if your stroke is not too long... (ie 377ci short stroke 400)... you can not lose with a solid roller.... they are the freaking BEST.... it feels like your engine finally breathes...
peaky, feel wize...it feels like your engine breathes...and revs...
