it made 815 and 760 ft lbs of tq at 7100...this was with the heads as he had them..very mild bowl work and a basically off the shelf older Dominater....the motor was built new by them and only had approx 75 passes...according to ron..everything else panned out he told me so i have no doubt to question him..the only problem i saw with the motor when i met him at his house was 2 broke inner valves springs..and it still sounded great......i got the motor really cheap..$4500...sold the dist and the carb for $500.00..so i had 4k in the motor..
so i took the motor home and had my head guy do a number on the heads..based on what my head guy says this should have picked it up 40/50 hp conservative if not more......bottom end ,bearings,cam,evertying else was perfect in engine..looked new..

so after i had my head work done i would say it was making close to 850 hp or a little less with the team "g" intake and gas..based on what i have heard i can expect a little more out of the 454-r ( alot of work done) and alcohol..i hear more TQ than HP on the alcohol..

anyhow keep in mind this is a 512 series block..came out of the 68,69,70 chevelle bored .125 over with a callies stealth 4.25 stroke crank..

i have heard from tons of people that you cannot run a 454 block .125 over without hardblocking..but i am here to say i do..i have ran this motor for 2 seasons and can run back to back passes and it never gets over 180 degree's...as YOU KNOW I ALSO RUN THIS MOTOR ON THE STREET AS WELL..( short cruise inns only ..no loooong hauls) geared to low..

My motor guy said the 512 series block was one of the tougher ones to run and bore..he told me of a story about a mutual guy we know that ran one for 6 years spraying it 200.....oh yeah its a 2 bolt block also...

the way i look at it..i have alrerady got my moneys worth out of it..if the block went tommorrow..i still have a 4.25 stroke callies stealth crank,crower rods.....and the heads are jam up along with the new 454-r intake and carb..
(if nothing in the bottom end gets hurt)...top end will be fine regardless.

i have already spoken with Scotty Duggins owner of PAR RACE ENGINES..he tells me he can put me together a complete 565 or 582 short block (dart big "m" block) for $5500..just bring him the heads intake,,etc......

i will save all the parts i can out of the 511 and put a 488ci in my wifes camaro and put her 406 on the floor..

so i got a plan if something happens..

so far the little 511 has put my prostreet 67 camaro (3,004lb) at a 5.99et at 114 mph with a 1.32 60 ft..
alcohol and 454-r intake is next..what will the little BIG BLOCK run ?

we shall see very soon....
