Well im finishing my build should go great..i have a GSR head fully built with skunk2 everything...type r tranny in hand also..now im on to the block..i have a LS block my local tuner wants me to try out a B20 he sais that it would be crazy for what im doing.my friend has a B20 for 350 he will sell me is that a good price?but ive heard alot of bad stories about B20's..what differences would i see between the LS and the B20? i figure if its torque well why cant i just take the LS stock 81mm to 82mm or so and gain a little..ive also heard that the b20's cant take any high rpm's? any info would be great
