Guess the horsepower on a little pepped-up 390....

Drew, I think it was Dearborn Classics.

Fryedaddy, I’ve been telling myself that I won’t sell it but you know how that goes.  It isn’t a pump gas motor though.  You’d have to mix, run E85, etc.

495 Ft-lbs. @4650
565 hp @6900

Grab up those 660's and spin it.

[Cyclone03]

572hp @7250rpm

538hp at 6750 rpm.

Looks great, but how many v/c gaskets you gonna run?    I'm guessing you will be using spacers? I have some of the 5/16" cork gaskets from DSC and fit very nice on mockup for my current build. I had to shim my HS setup about .240" to get everything happy. I also came out with about .050" sweep. Will also be using those same covers....

Always nice to see a 390 get some attention. Looking forward to the results.

No spacers needed.  Doubled up on gaskets because rocker stands were shimmed up quite a bit and I used some longer stand studs.  In the pic above the valve covers are not bolted down and I was trying both cork and rubber gaskets.

The valve covers fit with one gasket otherwise.

Great looking 390!
Love the FE's for sure.

537 hp @7000 rpm
470 ft lbs @ 5500 rpm

I think the torque numbers will hurt with the very early exhaust opening (@121 LCA exhaust timing)
But the power will probably peak later.

Cheers

Just a reminder to the guys, guessing on torque is not required. 

Peak hp is the variable here and if you want to shoot for the rockers, peak hp rpm. 

As for making torque, that's not something that I'm concerned about.  It's pretty much a given that a high rpm, small displacement engine will have considerably less torque.

where can I get that plug you have in the oil filler tube spot?

[blykins]

It’s just a 1-3/8” cup plug.
