That sounds similar to my 383 for my 70 Chevelle. Mine has brodix track 1's, 11.5:1 compression, a super victor single plane, 750hp holley carb, lunati 248/248 110 .592 .592 solid roller cam. I wouldn't pick either of those 2 cams you listed. You should have someone spec a cam out for you and get the lift around .600 where those heads really flow. I bet she runs pretty hard! These old sbc's really like alot of cam, but it just depends what rpm you want to turn.

^Agreed, youll make alot more power with a good amount of lift on those heads. I would suggest a cam right around .600 lift and around 244/252 on the duration, also keep it on a 108 as long as you are staying na with it.

and thats what I really wanted a cam that has over .600" lift and its a hydraulic roller cant afford solid roller lifters now I found this cam 08-470-8 it has .600" lift but I dont know should I go with solid roller or stay hydraulic roller?

For a street car I don't really think solid roller is worth it. You can make great power with a hydraulic roller setup and still turn 7000 rpm if you want. I was in HS when I built my engine and I found an awesome deal on ebay for my setup... $190 for new solid roller cam and lifters! I have full 4340 forged, studded motor that I have a NOS big shot kit for 300-400hp shot. I have a friend who also built a 383 with ported track 1 heads the big brodix single plane intake. He went for more of a NA setup but it has a huge solid roller cam 25x/26x something duration with over .630" lift. He runs a built 700 r4 but he has not had his car running long, less than 1000 miles on the setup.

If it was my setup, I would run the old 236/242 cam. 1. Because it's already paid for. 2. It's driveable and proven to work well. 3. I would add 1.6 roller rockers and sell the 1.5's if you can. The 1.6 rocker will make the lift jump to .550"/.570" and the ratio actually makes the camshaft act like it's 2-3 degrees longer in duration. So it would be like a 238/245 duration. roughly. I think this will work better than the larger cams because of the Dual plane intake and the 3200 stall. If you want a big nasty cam, you should also do a big nasty single plane intake, and a 4200-4500rpm converter, and sticky tires...still not sure what tire you are on....

This time around for my weekend warrior I was given 259/263 @ .050". 112 LSA, .664"/.664" Lift, Installed on a 106 Intake centerline. .014" lash solid roller. 11.5:1 Comp. 396 SBC.. works really nice to far!

Spins hard to 7300'ish.. Will be dyno'ing it this week if all goes according to plan. Goodluck!

some dude that has camaro 94 offered me a twice original price for the 236/242 so I let it go long time ago so I only have the big ***** stupid thumpr I think I will go with 08-443-8 I need some intake vacuum for the brakes and I will look around for used 1.6 roller rockers that clears 1.550" springs
