Rhett Posted September 10, 2011 Report Share Posted September 10, 2011 Going to buy a bare block here soon. I do not have a car yet, but there are a few cars I would like to do with either motor. I know a little about the 302/351 but nothing about the SBC motors... I just know Sams 350 in his boat always blew up. :gabe: It will be for mostly 1/4 or 1/8 maybe some low rolls. So I know the Gearing and trans will also be a huge factor. So Learn me Pros and Cons of both and what is some of the better common builds.

wnaplay1647545503 Posted September 10, 2011 Report Share Posted September 10, 2011 What Aj said. It seems like the general consensus is that a SBC motor is easier/cheaper to build and maintain. You even see alot of SBC motors put into kit cars, old rod projects because its just the easiest way to go, and its easy to find parts.

Buckeye1647545503 Posted September 10, 2011 Report Share Posted September 10, 2011 sbc>sbf sbc cheeper to build also. thats all you need to know really. This used to be the truth years ago but not really so much anymore. 302 block good to 500-550 rwhp 351 to 750rwhp as for any other questions it all revolves around 3 things a: how you want to use it (WOT most of the time or street car) B: How much room you have in the engine bay (351 and 350 both use more room than a 302) C: How much $ you want to spend Quote Link to comment Share on other sites More sharing options...
Cordell Posted September 10, 2011 Report Share Posted September 10, 2011 For the price of building an iron block LS motor I wouldn't even bother with a SBC, they can be made to work well and are tried and true but starting from scratch especially on a budget the LS has more bang for the buck IMHO. I helped my Dad build the 302 for his Mustang, and it's pretty similar to a SBC overall. They are more expensive to build then a SBC, to get good parts it's about what an LS motor costs. If you are starting from scratch then get a 351 windsor block as a better foundation, its just a better foundation. So its not just that I'm partial to LS motors, but they are so much better stock that to get the same power out of the SBC/SBF compared to a bolt-on cammed LS, you'll have more money in it. You'd have to buy some nice heads for the old motors just to keep up with stock LS1 heads. You could buy good used parts for an LS motor, that cleaned up and installed correctly, would make good power, and most people think stock LS1 heads, stock cranks, rods, even pistons should be replaced for power. It just depends a lot on how much power you want to make. Quote Link to comment Share on other sites More sharing options...
Rhett Posted September 10, 2011 Author Report Share Posted September 10, 2011 Ok, where I am at right now... I am looking into how much money I can spend. So I am pricing things at... besides forums where is good places to find Motors? For SBF and SBC I am seeing a million on CraigsList.. but what about LS_ motors and trans? Would LS1tech be the best place? Quote Link to comment Share on other sites More sharing options...

Would LS1tech be the best place? The best place for LS motors is any junkyard that does a lot of trucks, iron block motors are getting so popular in junkyards they are getting pretty reasonable. A friend just picked up a 6.0L complete with a lot of miles for $600, so after a rebuild it'll be just like the one in my car. Some basic machine work, rods, pistons, and wear items (bearings, chain, ect) I had just over $3k in a longblock assembled myself. Doing a 5.3 would be even cheaper and could be overbored to hold LS1 pistons. Quote Link to comment Share on other sites More sharing options...
pontiacfreak142 Posted September 11, 2011 Report Share Posted September 11, 2011 350>302 in pretty much every aspect. it will make more power for less money. hell i have my entire bottom and heads for my motor for a total of $1500 ish. i did get some stuff off friends for cheap, but other things ive also gone over board on (its a 383 for starters, so you wouldnt need that crank, and pretty much everything is forged) for comparison though, my dads cam in his 302 cost him a little over $200, and mine was like $170 Quote Link to comment Share on other sites More sharing options...

(alot i'll beat) now try that with a sbc...might be better off starting with a lsx tho. Quote Link to comment Share on other sites More sharing options...
dre2013 Posted September 11, 2011 Report Share Posted September 11, 2011 build a 5.3 or 6.0 iron block. cheap, and will put out more power and have better driveability and gas mileage than an sbc Quote Link to comment Share on other sites More sharing options...
