- 600 horsepower of pure Pontiac muscle. This is the 1971 455HO that I built to put in my Goat. I am pairing this motor with a Richmond 5 speed, and a Moser 12 bolt read end. I have waited 30 years (since I was 13) to drive this monster, and the time is almost here. Keep looking for more updates, and videos of the actual car build.

Music to my ears!
Nice real Pontiac engine!!!😀
In my opinion the light blue silver metallic engine color is by far the nicest color of any engine ever to come out of the factory it's a shame Pontiac, only used it for 4 years from 67 to 1970 !😞
Right on!
@Dean Williams - WRONG. - 1966 to 1970
Awesome Pontiac build
600hp using 1971 HO #197 Heads Even Ported by someone like SD Performance is a Tough goal! I built a 501 4.211" bore 4.50" stroke 1971 455 HO motor 5-6 years back HO block, forged 4.5 crank, eagle 6.8 rods, Ross 9.5:1 pistonsSD Performance Road Paver hydraulic Roller cam245in 252ex .660in .660ex 112* LSAFully CNC ported #197 Heads hand finished, very nice heads!They flow 280-285cfm intake and 228cfm exhaustPorted HO Aluminum intake manifoldCustom 900cfm Q-Jet and Hooker SC 2.00" primary HeadersAfter getting it broken in and everything tuned i managed to get 527hp at 5400rpm and 605torque at 4300rpm With a Ported T2 or Victor, and 10.25:1 compression it would make about 560-570hp and 620-630tq Its very difficult to feed a 455 enough air to spin it high enough to make 600hp ! Motor sounds great though! Good luck!
hi derek stewart thanks for the info on your build...i am looking for someone to port some pontiac factory iron heads to flow 270-280 cfm but it's a tough sell to the porters i have approached....most say to go with some aftermarket aluminum jobs....not my style...do you know of someone who could help me? thanks, john
p.s. your build sounds stout..
John Becay contact Larry Hansen, he's done 280 cfm. He doesn't really recommend it but he's done it before. He's in jersey and is a great engine builder. In Middlesex NJ
I saw a NHRA Superstock 1973 SD455 Pontiac engine make 720hp@8000rpm with the production based heads and Q-jet.
WHAT a LOAD of bad info.......dude, delete your post. Save face while you can
@@72troy455 Think you're in too deep with the canabis. Guess it had factory cast rods too.
It sounds amazing
How exciting
A RACING PONCHO MACHINE.GOOD SET UP.
Sounds awesome!! Looks fantastic.Where did you get the white belts? ;)
Love it! Just built my 461 with 518 hp and 555 tourqe. What is in it? Any dyno info?
600hp? Where's the data gathering equipment??
I hear Exhaust Valve Too tight on Cylinder #4 and Needs more Initial Advance Timing
Old head pontiac genius
Yeah and the t stat is too retarded
would love to know to know some specs on this beast
Need to adjust those valves! You do adjustments on the dyno not a stand
600 HP is hard to believe out of an engine that is a low compression engine with a cam that big. Sound a little slow in time on the stand. Do you have a vac. advance on the dist.
How do you know what compression ratio it has? Real easy to get 12-1 or more with a 455.
I seen a 73 SD455 Superstock engine dyno over 700+HP at 8100rpm. 950+lift solid roller, less than 10-1 compression. Original Q-jet on a Victor intake, cylinder heads are a masterpiece of porting and epoxy. It runs low 9s in the 1/4 in a 3rd gen firebird.
Seen a 455 with ported #16 cast iron heads, a warrior intake with a Q-jet, and a big solid roller make 630hp 30+yrs ago.
@@72troy455 Yeah, you blew your credibility with the "950+ lift cam. A Pontiac block cannot physically fit a cam that large, sorry Charlie.
Is it a 497 with Warp 6 heads on it? I see stock heads on it. Maybe 6X heads. If you port them up and mill the chamber volume down you should see about 425 horse. 600 is bullshit.
Those aren't 6X heads. If you can't tell D port 6X heads from round port heads you aren't a Pontiac guy. 600hp may not be the real number but with properly ported round port heads it is possible.
What r are the specs? Is it street friendly? What is the cam and what heads are those? Stock rods and crank?
Guess work supreme. Where's the proof 600 hp. Notice how ALL of my posts show the engine on the dyno AND the data.........tsk tsk
WHAT ABOUT A SINGLE TURBO FEEDING AIR TO IT. BALANCE OUT THE RICHNESS OF FUEL. BUT IT'S A RACE CARE ENGINE. LET ER RIP !
Makes a better video of it runs and sounds good
Why would you show this video of bad engine?
