April 1, 2005I have an oppourtunty to get a 454 and tranny out of a '90 gmc 3500. it should be fairly easy to shoe-horn it into my '90 1500. but i was wondering if the 10 bolt GM axle in my 1500 will hold up to the power of the 454? (im not exactly light footed).

April 4, 2005I agree with the General ..... If you've got a 'heavy' foot, that 10 bolt doesn't stand a chance ...... Also, you know what a cool thing to do would be? .... Take the axles out of the rear. Clean them. Tape off and spray paint a straight bright colored line down the length of the axles. Re-install the axles and drive the way you would normally drive for a few days / weeks. Then pull the axles back out and see if the lines are still straight. If they're not you know you've got some changes to make, either in your driving, which probably won't happen, or the rear's got to be strengthened or changed .... I've done this with plenty of vehicles .... You'ld be suprised to see how many 'candy canes' I've found .....
April 9, 2005thanks for the help, but i had to put a new/used tranny in it for now and the girls a lil old for that motor...i would need more time. i do have a 4x4 project that im working on that needs a motor (1980 blazer)...but again, its got a 12 bolt rear, 10 bolt front and big tires...so until i can get bigger axles it stayin with the 350. Thanx alot for the help
