Re: cam for 383

I like your idea,..230 duraiton. Comp's Magnum 230H works great with 3.73 gears and at least 10:1 compression. Good quiet cam, fairly smooth (it'll idle at 900), doesn't do much to 2500 but after that, hang on!

My opinion.

Re: cam for 383

Definitely. I just had that cam in a similar 383. Over 400 at the crank for sure. I loved the way the car drove as I will use mine on the street alot. Still have to pull the cam out of the car and look to see if the cam, lifter or valve spring pressure caused the ticking problem I had. I loved it though while it was alive. My combo has 9.7-1 comp ratio, procomp 200cc heads with 64cc chambers and Ferrea 2.02 1.60 valves and Victor jr intake with 750 vac secondary Holley.

Re: cam for 383

Just beware of clearance issues. When you start to approach 0.500" lift (at the valve), you may have problems with the rods hitting the cam. Small base circle cams are often used to prevent some of the clearance issues, but I'll leave it to the experts here if a SBC cam is good to use with flat tappets or not. In my friends case, he ended up use an H-beam rod to get around clearance issues.

Re: cam for 383

Take a good look at that Comp. Extreme cam XE274H. I had one in my 350. Reworked early 64cc stock heads, 9.6-1 compression 2500 stall 3.73's. Even "LOVED IT" great power and torque. good lopy idle. would be a little mellow in 383. even pulled 12.5" vacuum at idle.

Cool Re: cam for 383

Here is one for ya! I have 525 miles on my new 383 in my El Camino. I used an XE 264 hyd roller (212/218 duration and .487/.495 lift). I have 9.7-1 cr, 192cc SuperFlow alluminum heads that I ported, Air-Gap RPM intake, HEI, and 1 5/8 Hedman Elite headers.

This combo is very powerful yet mild mannered. It pulls very hard to about 5700 RPM and has a cool idle. This a daily driver for me and is backed up by a 700R4.

Re: cam for 383

I would run a 292 Magnum comp cam. But for you wanting a more mellow can. Run a 280 Magnum. It will run good and have a lope too. That motor will easily handle a 292 though with the comp, ci and head.
