They make 10 to 1 800 horse aluminum headed strokers motors all the time. Catalogs are full of them that run on premium. I had a 30 over 318 that made 477 horse on 91 octane Knock 1 point of compression out of it...... is what 3%-5%..... not sure of this combo, but those figures didnt make me raise an eyebrow.... at 500 inches with a roller cam

Seriously doubting these results on this build. Peak TQ and HP occur at awfully low RPM's considering the Victor heads. Like Andy said 87 for a dyno pull = BD. In car is different ball game. J.Rob

Peak TQ and HP occur at awfully low RPM's considering the Victor heads. J.Rob Along with the big intake and carb. The fender well headers do lower the peaks, but 5300 seems a bit too low. I dynoed a 505 last fall with a small hyd cam, rpm heads, and an original torker(which is not a high rpm manifold), and even that very mild combo made peak power at 5100. 542 with EZ heads, 440-3 manifold, and 1-7/8” fender well headers made peak tq at 4500 and hp at 5900.

J.Rob Cheesy Quesadillas with Spinach and Mushroomsi was thinking the same... i mean, i have doubts in such results on that build... or maybe there's something i can't understand?

My 505 makes 600 HP and sips pump swill 87 with no problems. CNC ported stealths, 10.63 CR and very mild hydraulic roller. I was more interested in big torque for the street. I try to run 91 no ethanol in it most of the time, though.

I thought it sounded too good to be true but I just curious if it could be done. Around 2010 I bought a 505 kit and non-cnc ported heads from 440 Source for my 65 coronet. The kit i got is a 4.250 stoke 4.35 bore -27CC piston I figured my compression would be around 9.7 if I mill the heads down to 80CC. Back then I was saving money to get the heads cnc'd and for the rest of the components for the build then I bought a house,then got married, then had a son, and am about to have my second son so so all my car money went to better causes. I am finally in a spot where i can work on obtaining parts for my car again. This started my journey into octane requirements and if I could tweak the rest of an engine to run on 87 swill and still make good power. I haven't been able to find much about any engines running on low octane and saw this guys build and figured I'd see if it was doable. I appreciate everyone's input! A 9.7 engine with 440 Source heads (good quench pad) should run on 87 octane IF the pistons are correct. You need to be close to zero deck (0.005 down or so) and 0.036 or 0.041 head gasket. If you do that it will work. Then you can play with cam timing and ignition curves and stuff like that but it should work.

Cool, thanks for the information Andy. I don't need a max build. The car will mainly street driven I would love to get into bracket racing but know that would be down the road a ways. I have no plans of ever putting a cage in the car so I do not need gobs of power. Im aiming for a fun easy on parts and maintenance street machine. Figured a cam like Hughes/Howard's around 242/246 .564"/.576" with 1.5 rockers would be a good fit but will probably consult with a professional and get a customer when it's time. I do find myself occasionally drifting in thought and going more aggressive... sell the stealths go trick flow 270s and start shooting higher! Yeah, me either! That went out the window... With that combo, 11.50's are pretty easy. My second time out I went 11.30's with a smaller cam than what you have listed.

Ill have a dyno pull in a week or so with a stroked 440 10:1 and 240 trick flows , hydraulic rollers and cast manifolds and six pak Cant wait to see - hope for 500 .. builder thinks 7. 594 lift , seems high , but I guess the roller deal tames it. Not sure how it all works — i hope it idles like my ol bob k cam Everyone involved says it will be tame and super reliable
Nice! Look forward to seeing you post the results! You'll have to let us know the street manners once you drop it in! What kind of lifters did you go with?
