Hey all, I just wanted to bounce some ideas off yall and get some feedback. Im lookin to buy a 69-75 blazer 4x4 to take off to school with me but im planning some modifications and want to see if maybe im going in the wrong direction. First off, im planning on pulling whatever drivetrain it has out and replacing it with the TBI 305 and 700R4 out of my 89 RS camaro that im parting out. Im not sure, but im guessing ill need new driveshafts for that swap, and perhaps a certain transfer case? if so a point in the right direction would be much appriciated. also, the engine isnt the most powerful, maybe 170hp and 255lbs/ft of torque, is it reasonable to think that would move the truck decently or do yall think ill need more power, maybe 250hp and 300-350lbs/ft of torque? im no stranger to modifications, so a cam swap and some headers and things shouldnt be too tough, but im on a bit of a budget so id rather not spend money needlessly, im not lookin for a race truck, but i dont want to have to shift into first gear to get up a hill either. I was an electronics diagnostic technition and corvette specialist at the dealership, so im very comforateable dealing with the electronics involved in adapting the TBI to the truck, so that shouldnt be a problem. but if anyone knows of this kinda swap and has some helpful hints, im all ears. Also, im lookin to upgrade to a set of 33in or 35in tires if it dosnt already have them. Any suggestions on a brand or specific tire? ill be using the truck to drive to and from college, and using it for transportation while at school. so probly 80-90% on road driving and in snowy conditions with offroad use whenever i get the chance but probly never rock crawling. and i did some reading on here and saw that for those size tires you need a 4in lift and some fender trimming. what kind of lift do yall suggest? springs, shackles, blocks? i did a 2in shackle lift on my jeep and it worked great, and was nice and cheap, is there a similar 4in lift for the blazers? and i guess this would also impact the driveshaft angles and length, any thoughts on that? although if i need custom driveshafts for the 700R4 swap anyway, i guess its a bit of a non issue. I was also wondering what kind of front suspension these trucks have, ill go hit up the photo gallery and see if i can figure it out, but while im asking, are the front springs leaf springs as well as the rear for this generation of truck? also, can these trucks run a soft top year round? or are the soft tops not capible of keeping it warm inside in the winter? i had a jeep and ran a soft top year round, but it was alot smaller inside and i dont know if that makes a big difference. cold dosnt really bother me too much, but im guessing other people dont care for frost bite. Sorry this came out so long, and thanks for everyones input.
