450-475fwhp, could be more with a better intake.

Well????????????????

 

[igo1090]

425. small cam, small intake.

 

[v8shadow]

Can I change my answer to appear wiser ??

 

[289nate]

With .205" intake and .160" exhaust valves I'd say about thirty horses at the flywheel (maybe less).

If you change those valves to a 2.05" and 1.60" I'd think more in the line of 500 hp.

What a privilege to have your insight Mr. Sunshine! You're most likely too good for this site and not just this topic. Did I miss something!?!

I agree that knowing the duration would be helpful.

Rough guess is 450-475hp based on the intake, which is known. You need to be careful with not adding too much duration if you need to run that manifold. The RPM will start to fall out early on the 408.

Would easily be 500+ with a Vic Jr and a decent cam.

289nate,
Mr. Sunshin huh? LOL. I was way off on my answer because I am not new to the hobby at all, but I am new with the respect of building and restoration. My answer was a guess. My reply was a joke. So chill.

Yep, you did! It helps to read every post/reply.

That would help alot. You need to keep on mind that the Perf and RPM were designed with a 351ci plant in mind and you're trying to feed an extra 57 cubes, which is roughly 16% more. This doesn't take into account the improved heads which will also increase VE.

Your two posts were misunderstood by me as an intent to be very sarcastic. Glad that's not the case. Sorry!

I'm happy to have you here judging by your other posts.

 

[289nate]

I did and think it's clear how I could have been mistaken. Again, sorry!

I would assume the cam is in the 235-245 duration at .050" lift range. The victor junior should do better than an RPM air gap with that kind of stroke. I also have a problem with the little 750 carb. I'd go bigger. If you already have it then use it. It'll do an alright job.

I'm curious to see how these heads do for you. Keep us posted.
