Thread: SB2 info needed

Tweet

Hi guys,
I don't post often but I am on every day and now I need some advice, Pat and Eric your help would be especially appreciated.
My son and I currently run a S/G mustang with a 377 SBC, injected alchohol. The 377 has Mahle pistons, Brodix heads, eagle H-beam 6" rods,s Lunati roller .645, GM steel crank...We tried to use good stuff but alas, we lost a lifter and screwed up one piston and one head. So now it's time to think about a new engine. I having been thinking for a while now, that with all of the good used SB2 parts on the market, it might be time to try one out. There are several companies in NC and Ill. that sell used complete sb2 heads for anywhere from $1000-1500 with rockers, and I see pistons going for $2-300.
so a couple of questions,
1. What do you think of the SB2 as a drag race engine?
2. Could we fill our current 400 block, bore to 4.170 (currently 4.155) use a
4" crank for 434cid, our 6" rods, water in the heads only, since we run injected alky?
3. Are the SB2 cam and lifters different than regular SBC?
Any suggestions?
John
