Need 454 Chevy killer street combo advice

Hi people, I need to get the rest of my parts for a mean street machine. It's a '70 El Camino, wide sticky tires and rearend set up to hook. I have a 3.55 rear gear and a 4 speed but might change to an automatic and about a 2400 stall someday. The engine will be bored .060", forged flattops, zero decked, stock rods but steel crank, plasma moly rings. Heads all gone through competition valve job with new valves and new guides and Harland Sharp 1.7's. What I need to know is what cam, lifters, valve springs, intake and carb would you guys recommend to complete this combo for a potent 450+ h.p. street mauler that will have a decent idle and vacuum. I don't want it to be a chore to drive on the street and take all the fun out of it. I was thinking about a range of 225-230 dur. @ .050" on the intake, does that sound about right? Also what oil pump would you recommend? Please advise on these parts.

Thanks,
Mark H.

What kind of heads do you have? Are they rectangular or oval, and do you know the casting number.

on the street i would stick with the 4 speed. also a big gear can ruin your cruise fast. just be aware. i never built a gmbbc, so i dont have any personal combo's. i like to go with complete packages. i run the hughes stage 1 in a 440 with a 4spd and 3.23 gears. it works on the highway @ 70. great burnouts. thrilling....spectacular performance, and powerful tire breaking downshifts! also the lower gears can bring the manual ratios too close together (i think at least).


i dont consider high stall and short leggs street. people here seem to love it. it will make the car FEEL lighter. im pretty sure if i didnt have to drive my vehicles, i d love it too. come to think of it , if you go OD , go nuts, have your 4.10's and EAT IT TOO. my integra has 4.10's, so does my toyota truck.

i have a 70 ss 454 4spd elcamino also.
mine was an ss ls6 m22 with 410 gears from the factory.
the motor and tranny are gone.
but i have herd there still around.
but where im not sure.
i took the motor and tranny out and put it in my trans am for now till i finnish the body on the elcamino.
i put the comp cams 280 h in mine its from around 2800to 6000 rpms.
and i have a action plus intake on mine with a 750 dbbl pumper and it runs 7.80 in the 1/8th mile.
that converts to a 12.25 in the 1/4.
i drive mine every day and it runs great and is very drivable.
but if i was going to change the cam i would go with a hydraulic roller around the same grind.
that would wake it up.

Intake

I have oval port heads, if I remember right they are '67 or '68 427 heads with small chambers. I figured the static compression and it will be about 9.5:1. Do most people go with a Performer or an RPM for the street with Chevies?

Thanks,
Mark

bah, if you're talking short distance, chassis is where you want to look. ANy number of combos will be good, but what will really make the difference is as high of a stall as you can afford on the street and some slapper bars/tuned chassis that will plant and go. You can make power all day long, but as soon as you spin the tires and your competitor doesn't, you're sunk. Races are fought and won at the starting line, not at the finish.

I would go with a Performer RPM with the xe274h cam( 230 236 @.050 .552 .555 lift 1800-6000 RPM), and a holley based carb anywhere in the 750-850 range. Also, this cam would work well with a stall somewhere in the 2500-3000 range if you ever put an auto in it. I think this combo would match your heads well.
