need advice on 500 stroker build

[smokie]

I'm building a low deck 500ci stroker for my 65 belvedere & I'm needing some advice. It's a street/strip car that weighs about 3800 lbs with me in it. I'm going to have 325/50-15's or 295/60-15's on the rear, 3.73-4.10 gears, 727 automatic transmission with stall matching cam, 4.15" stroke crank, 6.76" rods, 24cc dished pistons, unported Procomp aluminum heads (victor type) with 2.20-1.81 valves, & a weiand tunnel ram.

I'm would like to use a solid flat tappet cam, Hughes rockers (1.5 or 1.6?), & I'm thinking of using two holley 650 or 750 double pumper carbs.

The compression is 10.64. What cam & carbs should I use? I'm thinking of something in the 260-270 range @.050" lift with .600"-.650" lift.

What do you recommend? see anything i should change? i'm going to run a tunnel ram, i just like them.

I am not sure what street means to you ( 5 miles to the burger stand or 70 mile runs down the highway......either way, I see a problem here if you intend to go far....With an automatic, if you intend to go far, you need to keep your stall speed under your cruise rpm to avoid overheating the trans- with the tires you spec and 3.73 gears you will be at about 2700 rpm at 60 mph, 2975 with the 4.10. This means a stall around 2500-2800. I f you ar eonly goinf short distances you can somewhat ignore this , but the cam needs to come in below the stall or it will be a dog off the line. Around 250 @ .050 is about 2500 rpm on the start side of the power band. 270@.050 is about 3500-3800 on the bottom meaning a 3700-4200 stall. Also the .650 lift is quite a bit for a street motor- valve springs could be an issue if you are going long distance....In short, I need to know more in depth what your intent is with the car. Tunnel is fine- I run one on my street car- I would do the 650's for the street for better response -750;s may give a little more over 6800 rpm , nut you won't see it on the street. Why not a solid roller? With today's oil, I would think it might be better and as an added + you can use a shorter duration for better low end and because of the faster ramp, still get the same of better power......If you want to elaborate on the exact use, I can be of more assistance.....
