What motor to build?
 

As racing season ends time to build another motor. would you build a sbc a good 383 stroker or a 406 with good 4340 internals. Our would you build a 454 bbc and turn it into a 496 or a 509. Cause a rotating assembly is about the same. I no you cant turn a sbc into 434 without getting a aftermarket block. How big can you go with a stock bbc. You can get a short block for about the same price. well almost the same price there is about a 500 to 700$ differnce. My goal is to have a motor that does not cost alot to run.

Big Block hands down.

Question is..How much are you gonna allow yourself to spend on a motor ?

this will tell ya if a BBC or SBC is on the menu.

How big can you go in a stock block? How much horsepower can you pump out of a stock block? You can bye a bbc short block for about 4500 . But it comes with a dart block or a world block. i have a vega wagon 2440lbs with me in it and a sbc. it makes about 450 to 475 hp. it runs 6.70s in an eight mile. but we are still tuning it. I want to run low 6 or high 5 with out turning it to hard. So how much hp do i need?

To answer your 1st question..stock 454 blocks have been .125 over.i owned and ran one...it is getting a little risky ( thin cylinder walls).....125 over with a 4.25 stroke crank made 511 ci..with bb2 heads and matched 454r made 800/850 hp..i along with others on here would feel much better at .100 over (max) with a 4.25 stroke...without using a wallace calculator etc..i am thinking this would put you in the 505ci range..

Now its hard to say where this would put your car ET wise..too many factors to determine this( chassis working ,gear,tires,tranny) etc...

but i will tell you this and here is a time slip and video of my 67 camaro street driven prostreet car at nearly 3100 lbs ran a 5.99 et at 114mph with a 1.32 60 ft with this stock block .125 over..

yes definatly ! you can get a decent BBC chevy short Block for $4500

this gives you an idea how quick my 67 camaro was with the 511ci for a Heavy street driven car (3100lbs)..the guy beside me was a 6.40 et DRAG CAR car at 2400lbs

so yes your 2400 lb car will lay it down if done right with the BBC

5.18 gears 2speed powerglide and 32-14-15 tire. When i go threw the light at an eighth it is 6500 rpm.It also has strange axles and trans has been gone threw and been replaced with new race parts. It has a nos on it but not hooked up. it is a 200 shot

bjuice,that car seems to go o.k.,but man your reaction time? :lol:

i'm old Dude !... i came from the days we had a flagman... :roll: ..lol

i am seriously thinking about a transbrake and electric shifter this next year...No way i am gonna try one of them thar Boxes... :roll: :?: :idea:

If you go bbc, you will have to get new headers, oil pan, valve covers, etc. Just something to think about. A 377 with good rods would put you where you want to be at that weight with the right top end, and be maintenance friendly, to boot...

Very Good Point all the way around !
