SB vs BB who wins?

-
I prefer small blocks, just because I prefer them. LOL

I'd like to put mine in a feather weight car and see what it would do, it's been 135 in my 3292# Dart, on pump 93. It really doesn't fit the spirit of discussion here though as it's 434".
 
I think the engines can be as Bad as you want them to be.
 
I've had a pile of small blocks, so I'd go with a stock stroke 400.

I have a 406 that a semi-smart chimpanzee could put together, in a 2300 lb car. Went a best of 6.32/108.5 with maybe 500 crank hp
I'd guess your 434 at around 650, so.......very low 9s at 145 in my car. Maybe a high 8.
 
If we are talking stock big block vs stock small block. I will take a 340 over a 383 or 400 any day of the week.
Okay , hypothetical for you.
340, 10 to1,190 trickflows, Victor 340 intake 750 holley or
400, 10 to 1, 270 trickflows, victor maxwedge, 750 holley
All off the shelf parts, all available.
Appropriate headers for both, in a same weight duster (ballast the small block to make it fair )
Now which would you take?

At 2300 pound I can guarantee you I would be 8.90’s.

That big block combo may be better off with the 240cc head.
 
Could be.
Probably depends on cam specs and rpm range. Gonna use Victor's on my 522. Bought em before there was such a thing as trick flows. 270s would be the no-brainer choice now.

Ported victors are probably better than the 270’s
 
......probably cause you can slap a turbo on a 5.3 LS, and make the same power as a 600" big block chevy..... for about a quarter of the money.




...for a little while anyway. Five laps?
My buddy has a 5.3 junkyard engine with a turbo on it, its been together for several years, nothing fancy, 698 hp at the rear tires.
Its in a truck, he pulled out of the junkyard, he fixed up the truck, he painted it, has less than 9K in the entire truck.
A lot of time, but not a lot of money spent. Its reliable, and he daily drives it in the summer.

This an old racing buddy of mine's car. 80sMalibu, with a 408 LS and a turbo. Just under 1300 at the crank.
It's soon gonna be his slow car.

The 400, but with a Holley HP950.
 
This car has a basically stock 440 with a small flat tappet cam, aluminum intake, absolutely nothing fancy, and it will run 9.90 in the 1/4

Solid lifter cam, aluminum intake, who knows what else.

Mildly ported Iron heads (No offset rockers or epoxy work), small valves, cast pistons, stock rods, steel crank, Isky rockers, 93 octane pump gas.

It's really a very plain vanilla basic engine.
