No, the 1.8 rockers won't help. I tried that on my Comp Cams 212/218.

 

Longtubes and Comps 212/218 .522/.529 is what I have. I just met up with Justin today and got everything all tuned in. It makes sick TQ right at about 3000 rpms....right where we need it when we tow.

For comparison, I have a 2500HD with 265s and 4.10 gears....sorry I dont know how to fill out a sig on this site.

 

could some one explane to me how lob seperation moves the power band up or down. looking at the cams some are on 112 and some 114 or 115. cams are something that i have never studied on and i see now i need to. thanks for all the good info, please keep it coming,
matt

 

Here you go, LINK.

 

You could shave the heads alittle to bump up the compression....

 

You might consider lowering You're static compression ratio a little , I'm sure You're aware that the higher the scr is the higher the rpm's where the hp and tq peak #'s are , so the opposite is true without sacrificing any more than say 10 or maybe 12 ponies at the top end , but You would see more tq in the bottom to mid r's especially with a cam ground specifically for low to mid range tq. Also , lowering scr lowers You're engines octane needs , iow , You're computer can advance ign timing a little bit more without pre-detonation adding a little power all the way through the rpm range , on reg unleaded . Good luck and happy tractor pullin

 

I have the 206 cam and it still lacks below 3k but not as much as stock. At 2500-3000 rpm it picks up good tho. Get a good spec cam and pnp heads by someone that knows what they are doing. Should be able to help down low a good bit but they have to keep velocity up. Also the tune and tri y headers would be good. Just my thought on it if you dont have the funds for a supercharger you could do the above little by little.
