That low rwhp is 100% the cam, intake and headers

you put a 302 cam in there and got 302 power. no surprise.

347 cam and Longtube headers and better intake like a Holley or Trickflow R
will put you up in the same HP I'm making............350ish rwhp

I have a CompCams "Ford 347 stroker roller cam" 236HR-14 $250 at jegs
You need 145# springs professionaly installed for it though.

 

Sorry but what do you mean about leaving power on the table. What could I do different?

 

347 needs a LOT of air to breathe properly to make the hp its capable of.
the parts you have only let it breathe like a 302 so it made 302 power.

Will have to have springs on heads upgraded to 145# seat press. springs also.

Intake:
Holley Sys II intake - Best Flow I've seen, wish they made one for my engine
TrickFlow R is next best - what I have.

Long tube 1 3/4 headers on the exhaust side

Those parts will open up and let your stroker make the "top end" power
at 6,000 rpm its capable of.

Notice how your power band stopped at 5,100 rpm ?!?!?
Thats cause thats where those parts maxed out with what the stoker was wanting/needing
Those parts will allow engine to breathe up to 6-6,500 rpm and make more power up top.

 

It's means you have more potential, but you chose to leave some potential power on the table with the poor selection of parts. Throw that junk cam away and upgrade the intake.

Does this motor have flattops pistons? With a decent 10-10.5:1 compression, you should add 80+rwhp with a few changes.

 

yeah bud your cam and intake is not good for that combo, with my 347 i put down 373RWHP and 427 lb ft TQ on the dynojet with XE282HR and RPMII and everything else
