Mine dynoed 349/349 also lean up top and hit 11 degrees of false knock but not bad for porting the heads myself

 

Got a dyno sheet you could post??? I'd like to see how that curve is.

I'm actually expecting to see 390/380 with the 1.7 setup on mine.

I'd figure the Hp to be a little higher on your 383 though.

 

My car is only driven about 1,000 mile a year, so valvetrain wear isn't really a concern. I like that moderate profile with + .600 lift!

 

I can't find the dyno sheet.... I know it's floating somewhere on the net and on one of my 3 comps....

FYI, I built the motor NOT for high HP but for TQ... i.e. street car. I drive it everyday in LA traffic. I KNOW i'm giving up some HP through the exhaust because when I uncorked it at the track, I lost 2 tenths and gained 2.5 MPH. That's gotta be 20 HP or so to the wheels.

I'll keep looking for the dyno sheet and if I find it, I'll post it.

 

Here's my dyno sheet!

Wow, that's pretty nice. I'm betting there's a happy medium somewhere for your exhaust setup to extract the most out of both.

 

I already attract enough unwanted attention (i.e. too loud) so i might just leave it as is. The exhaust I would get is a custom 3" w/ X-pipe... but thats $700 and even louder! 20 RWHP for $700 isn't a good return. I might just install elect. cutouts for the track and call it a day.
