calling all 350, 383, 400, 406 guys...NEED INFO FAST Will anybody who has these motors give me the hardcore facts on these dimensions:[list=1][*]bore diameter[*]rod length[*]piston height[*]crank stroke[*]wall thickness (cylinder edge to waterjacket)[/list=1] I am attempting to explain to someone the differences in the motors but they do not want to accept my word, so please give yours. I want to hear from the mechanics who have built them. Otherwise if you have built your own please tell me only the dimensions on your motor. I am not trying to sound like a jerk but I want to have the facts from the people who COULD PROVE it. That way I cant be wrong. THANKS GUYS :hail: |
ALSO, if any of you 400, 402, 406 guys can go to the "cooling down" forum and clarify the overheating myths, it would be GREATLY APPRECIATED, too. THANKS |
383: bore=4.030" stroke=3.75" 350: bore=4.000" stroke=3.48" 400: bore=4.120" stroke=3.75" 406: bore=4.150" stroke=3.75" The 400 has a special rod length of *I believe* 5.565", all others can be used with 5.7" rods or 6.0" rods. I myself have a 377 going into my vette, which is an untouched 350 block with a 383/400 crank in it FYI and i'm using 6" rods. |
The 400 came from the factory with 5.65" rods, however it can be built with 5.7" or 6.0" with the right pistons. The same goes for 350, 355, & 383's. Here is some info from Trick Flows catalog: Disp. Bore Comp Ht. Stroke Rod length 355 4.030 1.555" 3.48 5.7" 355 4.030 1.250 3.48 6.0" 383 4.030 1.420 3.75 5.7" 383 4.030 1.120 3.75 6.0" |
