i've decided to switch out my sohc to a dohc but was going to add a street/track comp cam, mopar pcm, 10.5:1 compression pistons, ported and polished cylinder head. along with titanium valve springs and retainers, clutch and flywheel up grade. any idea on horsepower gains??
I'm looking for at least 160 to the wheels.

 

You will need more than that to get to 160 at the wheels.
After the switch to a DOHC you should be about 115 at the wheels. Mopar PCM adds maybe 4-5 and the 10.5:1 pistons along with the ported/polished head who knows, but that won't get you 50 HP...thats for sure.

 

what gains do you get with the comp cam

 

Depends on the specs.

 

CHR-250-6

$429.95 pair

Radical Street/Racing profile, Super Strong mid-range and top end. Street/Strip cylinder head porting. Use Header and low restriction exhaust. Ported intake w/low-restriction air intake system. RPM range: 2,000 - 7,200

 

forgot to mention UDP and 60mm TB

 

Can't say that I have seen a Dyno just after the Crane #16 cam was put on, but I'd guesstimate maybe 10-12HP under ideal/peak conditions maybe.

 

so will it be safe to say i'll have around 130-140 at the wheels with all the modifications

 

I wouldn't say "safe" to say, but you could probably estimate it around there.

 

i could live with that....................... until i go turbo. thanks
