I pulled 500 FT lbs @ 4300 RPM and 500 HP @ 6000 with my last 351C .030 over, ported factory heads, Almost a .600 lift cam 9.8 to 1 comp, ported Torqer.
Things that hurt were Chevy rockers and thier bad geometry reduced lift, intake and 850 BG were too small.
Factory heads ported flowed 330 @ .600 lift, Intake dropped flow to 290, rockers dropped lift to 270 flow numbers.
No real tuning was done while on dyno.
Engine was going in a Pantera so was stuck with the intake. Would have pulled around 650 with correct rockers.

I agree, 950 carb with a tfc intake or the new afd intake would work much better, plus bigger 1 7/8 headers would help to push it past the 600hp mark easy IMO. Custom cam would have been a better option aswell.

Just had a buddy who built a 434ci small block with CHI heads on pump gas.............made 780hp & 620tq:eek::eek: going over there this weekend to check it out!!

The Shelby Mustang motor mentioned was hitting 650 RWHP but shut it down as it couldnt be held down as mentioned and was my DD for years.

Did port a set of Yates heads for a guy about half ported. Was flowing 360 CFM dont remember the lift. Absolutle the quietest heads at that flow of any I have tested or ported. He pulled 720 RWHP it was to be a DD too.

You have to pretend C motors are big blocks and require like 2" or better headers and 3" exhaust.

Have ever played with or built an engine with the aussie CHI heads?

Also have you seen the new CLEVELAND block by ARROW?.....4 bolt mains, thicker webbing, better oilling system so they say.

Its cast in China, but machined in WA, Australia. Looks to be a nice block.........i think around $3200-$3500 aus dollars. Dont know what the max cubic inches are.

Cheers, Bob

Chit trickles downhill, if his personal shop doesn't care about QC do you think his 3rd party supplier will? Also the guys on the cleveland forum don't seem very excited about it and finding good blocks are the biggest draw back to that motor. They are excited about the new Arrow block and the "Buttermore" block.

All that said, I would love for the actual Titus block to come to fruition and be everything its claimed and to prove me wrong!

Would make more power with a good carb. One that Barry Grant never touched. I'd throw his carb in the trash where it belongs. Once he messes with one there is usually no fixing it, it's junk. That man is a sorry excuse for a common hack and knows NOTHING about carbs. I wouldn't even let him turn the screws on my lawn mower engine let alone mess with a automotive carb. I heard he went bankrupt some time ago and hope for the sake of people that know no better of his INCOMPETENCE he stays that way.

No, I have not been banned. Im not that computer savvy, and theres some kind of program or firewall that will not allow me to join Network 54...even though I think this site is also a N54 site, but it wont let me access any new ones.

2 slow, whats the problems with the aluminum blocks??
