They should be back end of the week or earily the fallowing. heads are going to the machine shop moday. Or should I give comp cams a call and have them make me a custom cam? its really not that much more vs 1 of thier stock cams ( unless you go wild)Īny help you can give me would be most helpfull.
I have been looking at the comp cams spec sheets-all that did was give me way too many choices :hammerhead: from what I have been told by some old time poncho guys that the motor will make between 400-450. nicson logs with elbows What I am looking for is something that will be able to pull a skier np and still give me a good ammount of top end. its going into a jet boat with aggressor bronze 1.5a ( will probly be cut down to A but still free impeller is a free impler) orignal torker edelbrock intake.(or should I go to a duel plane?) blue printed and balanced.
Pontiac called 3.90, 4.11 and 4.33 rear end ratios a 'Performance Axle' option and the cooling system was not capable of cooling the engine if the vehicle was equipped with those ratios. 9.78 to 1 comp 750 dp( coming soon) 1.92 in take, 1.66 ex. If you install lower gear ratio such as a 3.90, your engine will run hotter at normal highway speeds. I am looking for help on picking out a cam for my 421.Ħ5 421 ~ 60 over so 433 ci.
