Heres my non-professional opinion.....4 bangers sound like sh*t

Josh, you should attend a Pro-4 stock car race, the sounds from the smaller engines running hard is incredible.

We use to run an Olds Quad-4 with a stock bottom end, Ross pistons, custom ground cams, port match only and dual Weber DCOE 50's, getting about 325hp @ 7800rpm 

There was a few tracks giving us a hard time about exceeding 95db at 100' 

Sounds like we grew up in the same era Josh. In the days where a spoiler chopped 2 seconds off a civics 1/4...

As for that Jr. intake I may be buggin ya for it... Someone at work crashed their Cobalt SS and offered me the engine/tranny last week. So I've been buggin Dave about the Jr. he's not so enthusiastic these days.

In my era, spoilers came on 69 Camaro's and civics was a class in highschool.  I'm feeling old...

I know the feeling...  AND you could do a 10 second quarter mile on pump gas at 23 cents a gallon.  Oh for the good old days again!  I had a 68 Camaro that had a spoiler on it.

1ST car I had was 67 Mustang convertable 3sp stick with 6cyl. Yellow with black top.. $150 (no rust or dents), next car was a 69 Camaro DZ302 burgundy with white stripes, black hounds tooth interior. $3200. (I wish I had that still) The guy who bought it from me, still has it. One of the main reasons I bought my Tahiti, besides being extremely clean, was the spoiler on the back, reminded me of the Camaro.

Rounded.

I'm glad you have seen the light on this. I read this thread last week and decided to sign up just to give you my .02. But it look's like you decided correctly. You can get a ton of HP/Trq out of a stroker small block.

Rather you choose a 383, 408 or a  406 (.030 over bore 400) with the correct set of heads and the right cam and intake you can make some very good number's.



That's a copy of a 409" Ford Windsor that I had built a few yrs back. It might be more power than you are looking for , but something in the hp 585-600 range is not out of the question for a 406 or 408 smblk Chevy wth the right parts choosen for the job.

Nice Numbers!  We need to compare notes, I may have under estimated mine.  I supose with out a dyno pull I'd rather aim low however.  Which AFR heads were they and did they have additional work?

The heads are  CNC ported AFR 225's w/ 2.08" int. The intakes stalled at 308 cfm at .600 the 2.08 valve would have flowed more with a .030 or larger overbore that would have unshrouded the valve.

This engine also had a rather radical Roller Cam in it. I don't even remember the numbers on it I'll see if I can find the ballpark number's tomorrow. This engine was my Engine Masters engine, it had to make power from 2,500- 6,500. It's not a cam that you would run in a boat or  car because the ramp speed is wicked, you would beat the hell out of the valve guides in a short amount of time. Shorter duration and very high lift for the duration.

I'll post another dyno sheet with the dual plane RPM-Air Gap intake. It lost top end HP and picked up some serious trq. down low.

And small Ford's too...

What recipe would you have for a 585-600 hp SBC?  What kind of reliability could I expect from a motor like this?

Do you want to not touch the engine or are you okay with adjusting valves on a Soild Roller ?

Pump gas or mixed (91/race gas) ? What rpm range?

Sleeper CP 

Pump gas, I'm sure I could learn to adjust valves.  What RPM range is reliable?  I'm 47, haven't touched a motor since I was 17-18 yrs old. That's kinda how this thread started, was to build something with my 12 yr old, the BBC I bought a few weeks ago.  As you can see, I think we've changed our direction.

R/C Josh is probably chillin with the Fam but he's talkin bout Duane at Hitech marine I belive He'll be back on line tommorow !! DAD 

If we were talking a smblk Ford I could rattle off a bunch of info off the top of my head. If this is something you would like to do with your kid you might want to buy a stought short-block 408 or bigger and then get  a hydr. roller cam and the heads and put it together. I'll look for some short block info for you.

I'll ask Dan Crower and my friend Geoff Mummert what they think. I would think you can safley do 10.5:1 if you go hydrl. roller you will be pretty much
limited to 6,500 rpm's. I'll see what they think about a 10.5:1 408 making 585 hp. That would be 1.43 hp/cu.in that's a pretty well built engine.

I'll get back to you.

Thanks CP, I appreciate you taking the time.   R/C

   SUGGESTION BUY FEBRUARY POPULAR HOT RODDING MAG IT IS ABOUT A PUMP GAS SHOOT OUT LOOK AT SPEC ON MOTORS WHAT SIZE AND HOW THE WERE BUILT THINK ON COST FORD MOTORS USED FORD CRANK AND FORD BLOCK NOT AFTER MARKET, NOTE  WHAT ONE PUT OUT MOST HP WITH FACTORY PARTS NOT  HIGH COST AFTER MARKET LOOK AT CAM , CARB, COMP,MOST RAN 10.43 FOR PUMP GAS THEY RAN. NOT TO GOOD FOR BIG BLOCKS. THEY WERE THERE ON THE DINO FOR THE MONEY NO TO BAD $192,000 READ AND THINK NO BIG PORT HEADS MADE IT?

Sounds good. Drop me a note anytime you like.
