my trans am runs 7.80 in the 1/8th mile with open headers and slicks and that converts to a 12.25 in the quarter.
i think thats a fast street car.
and is very driveable.
i tryed it out last week with my G Tech pro and it said i did a 12.79 was my fastest time and that was with the exhaust on and slicks.
im happy.

1970 SS 454-4spd elcamino 410 possi.1980 trans am CBB4spd 410 possi.

Big blocks are junk?

A semi stock 454 will run 12s in a light car with out expensive parts and steep gears. The big block will probably last longer and be more fun on the street because of the low end torque.

I have ran high power small blocks all my short life and have ran 10's with them, but I just built my first Big Block for one reason: money. Get to making 600 hp and you are looking at the limits of a stock casting small block... especially if you run 400's. A filled 509 casting 400 with all the money in for aftermarket caps, splied mains, etc. really adds up and so do the 3,000 dollar aftermarket blocks. You can take even a 2 bolt main 454 block... add ARP studs and be set to 1,000 hp.

To get back to the subject at hand... What I would do would vary by what you have. I would add ARP studs and get some forged pistons when you rebuild the lower end. A set of closed chamber oval ports like the 215's work very well with some work done to them and shoot for 10.5 or so compression. Keep the headers modest for a street car with 1 3/4 to 1 7/8's primaries and get a cam matched for your combo... I recomend Comp Cams XE series. Top it off with a dual plane intake and you should have a great driver or if you want to race... throw a 150 nitrous shot on it cause she will take it.

You are on crack foestauf

You need to put down the crack pipe my friend....

Come on now... Give me 5K to spend on a big block and you take 5K to build you a small block and then we will meet up and see who builds more power.

You are on some heavy stuff if you think someone has to spend 12K on a BBC to keep up with a small block.

You need to stroll around the pits some more or go to some real races.

Sorry I'm too anti-big block.
Big block means big dollars and that is all.
It's far too sad to see guys that spend 10's of thousands of dollars just to make thier big blocks keep up with small blocks.

One of the big issues with BB's is thier heads, the heads on them are just crap. Don't know how many of them I've seen goto crap.
Every thing you do with a BB is twice as much as SB's. And you have a lot more mass to get moving.
So you can take the big block, spend 12-14 grand get a good going 500hp machine. Or you can take a small block, spend 4-5 grand and get a good going 600-700hp machine. Take your pick:-)
