Looking for a street cam in the 350-400 HP range for the Heads and Intake combo that I have,preferably Lunati. The heads are rated for 1500-6500 RPM. I'm gonna put a TH350 behind the motor,gonna have the rear end done also.

Which kind of cam requires less maintenance(Valve Lash)? Roller or Flat Tappet?

I plan on driving the car everwhere,lots of highway driving to and from work also so I'm thinking 3.36 in the rear,is that a good all around gear?

Voodoo Hyd Cam - Chevrolet Small Block 268/276 - Lunati Power Would this be ideal? I wanna run a stock converter in the Transmission though.

Voodoo Hyd Cam - Chevrolet Small Block 262/268 - Lunati Power

High Efficiency Cam - Chevrolet Small Block 272/272 - Lunati Power

Street Master Cam - Chevrolet Small Block 276/276 - Lunati Power

Street Master Cam - Chevrolet Small Block 276/286 - Lunati Power

Those are just a few of the cams I narrowed it down to,any input?

327 cam selection

Lunati 50143 - Lunati Hydraulic Roller Tappet Camshafts - Overview - SummitRacing.com Howards Cams 113215-10 - Howards Cams Retrofit Hydraulic Roller Camshafts - Overview - SummitRacing.com Howards Cams 111145-12 - Howards Cams Retrofit Hydraulic Roller Camshafts - Overview - SummitRacing.com Lunati 60112 - Lunati Hydraulic Roller Tappet Camshafts - Overview - SummitRacing.com Lunati 501A3LUN - Lunati Retrofit Hydraulic Roller Tappet Camshafts - Overview - SummitRacing.com I would use a 355:1 rear gear. I had a 92 Camaro and that the gear that was in it. Had good pickup from a standstill and good top end too. If you are not worried about correct #s a 8.5 rear from any 72-75 Nova and 76-79 V8 Nova is a direct bolt in. They are called the big 10 and have a 30 spline pinion and 28 or 30 spline axles. Just as tough as a 12 bolt.

I dont know,I heard they need valve adjustment's more frequently.

Heres one that interests me: Voodoo Retro Fit Hyd Roller Cam - Chevrolet Small Block 270/278 - Lunati Power

Also this one: http://www.lunatipower.com/Product.aspx?id=2607&gid=147

Can someone plug my heads,carb,intake and either one of these cams and give me a power estimate?

Decisions,Decisions! Thanks for all you're help.

A upgraded 8.2 will hold up just fine with what your doing. 336 or 355 would work great. If you really wanna upgrade the diff save your money and look for a 67 to 69 12 bolt.

That sounds like my plan,gonna upgrade the parts and throw either one of those gears in.

I think I decided on which cam to use: BareBones - Chevy Small Block LT1, LT4 Hydraulic Roller Cam 276/286 - Lunati Power

Heres some pics of the car

For anything 327 with aluminum heads, I wouldn't run less than 10:1 static compression. That would leave at least a 9:1 effective compression ratio, less than that would be disappointing in a 327. The Edelbrock Performer RPM would be a good choice for your 327. You don't need big ports or max airflow, just efficient balance for your combo.

Tom is right. Tame your enthusiasum a bit, remembering this is a 327. If you want really big numbers change to a 350 or a 383. The 327 only needs about 90 % of what a 350 does to get similar behavior. In this case behavior and performance are different. Smaller heads, a slightly smaller cam, good chamber design and proper compression will create a drive anywhere combination that offers good performance.

That little cam should put you in the mid to low 14s with 3.36 gears

Aluminum Heads for Mild 327?

Assuming you are going to use forged pistons I have done some calculations using ICON Forged Pistons from Keith Black. They are the newest thing out, my machinist recommended them to me when I did my 454 build last year. First set of calculations are 327 block bored .030 and decked to 9.005, 5.7 rods, IC792 FT pistons, Fel Pro 1010 head gaskets, Lunati 10030 HYD Roller Camshaft, Edelbrock Performer RPM heads and intake, and a 750 cfm carburetor. The static compression would be 9.796 and the Dynamic Effective Compression Ratio would be 8.465. This setup would produce approx. 390 hp and 412 lbs. of torque. The second set are 327 block bored .030 and decked to 9.005. 5.7 rods, IC793 domed pistons, Fel Pro 1010 head gaskets, Lunati 10030 cam, Edelbrock Performer RPM Heads and intake, and a 750 cfm carburetor. S/C 11.072 and DCR is 9.588 which I think is too high for the street. Flattops are the winner.
