SB2 in a super late?

[andy16]

i wish it were that easy. if each of the heads were the best they could be with the best combo possible it would be very close. im biased to the sb2's because theyve worked well for me. i never drove anything before and i started w sb2 stuff and id say it was as easy to drive as 18* or 23* although everything happens alot faster w the better motor. the lowest hp motor will def be the easiest to drive because your slower u dont have to worry about wheelspin and u wont use as much brake to my experience. so i guess the 18* heads would drive the best?i see alot of cars win with each of them from the best of the best to guys like me. sb2's just got a bad rep from people taking them right from a nationwide shop to there dirt car. id say a quality combo would be more important than just wich heads. if your not sure go to your local track and take a peek around at whats winning where you want to race, around here u see it all. remember no one part will make a difference its about combinations and power complimenting.

Now scuse me if I'm wrong here but, I always thought that the SB2 was basically a GM copy of a 90's Yates Ford head aimed at making Chevy horsepower comparable to the Ford and 18* Pontiac in NASCAR races back when. Couldn't ya just build a Ford? I think I jest threw up in my mouth a little, and get the same effects? If it's cheap I would do it but what are all them NASCAR teams gonna do with all them completely useless Dodge engines next year? I'd be willing to bet they'll go for next to nothing and they are brand new tech. Being poor I couldn't turn down a great deal though.

Low horsepower engine won't blow the tires away, huh? Andy I need to get you to look at my car for real man cause I don't have 900 HP and my little bitty garage built stove will crush them. (maybe I'm a lot better at motors than I am with chassis though).

im really not good enough on the chassis side to be tellin anybody anything and seems like everytime i open my mouth about somethin i stick my foot in it, everytime i try to help somebody turns into a mess. im gonna be like a racing hermit this year at the track, keep my thoughts to myself self this year sept for a few questions on here.

i believe they came w the splayed valve head first to compete w the ford but nascar declined that design because it was a symetrical port just like the ford and nascar wanted gm to keep its middle exhaust ports together so it looked like a chevy motor so they started over, mirrored the ports moved the valve arrangement to I E I E E I E I from E I I E E I I E to try and help the manifold w a single carb design kept the splayed valve and was a compromise from what gm wanted to what nascar would approve. later gm got what they wanted w the rox engine basicsically a symetrical splayed valve head w a 4.5 bore spacing . personally i think they took a step back from sb2 i dont see how a symetrical port design is better for a single carb but hey? they have a 4.5 bore spacing sb2 now and if i were a cup builder id be pursueing that route? but now theyl all look the same and basically are the same. alot of this technology came from comp eliminator drag racing and never to be pro stock truck racing, i would have liked to see where the sbc would be now if that class had came to be??

the dodges make good power and prob will be cheap but they are a heavy motor, the heads are heavier than sb2's and the block is way heavier its a skirted block w side mains, will be very strong but heavy but for the price who knows. i know alot of people who told me my sb2 was a waist of time and money and its still here and never let me down season after season and they arent racing because they blew up motors

My SB2 motor dont have to be ran hard or be kept in the higher RPM's to run. Granted mine made a lot of torque mid range (639 at 5000 and peaks out at 661 at 6100) only thing ive noticed is it dont want to stop when you lift it just wants to shove you on in the corner so a little more brake was needed. I love mine and for 13,000 fresh rather than 18,000 for a 430 9 degree that has 750 laps on it.
