Okay, hi everybody! I'm new to forums and i happen to have a question for you guys.. i run a small shop and i usually find myself towing cars down to my garage. My truck is a 93 4x4 blazer, it has over 263,*** on it, 5.7 TBI and a 4L60E trans and a 10 bolt rear with 3:42s in it. I already know my motor is shot (timing chain is stretched by 12 degrees, and my compression test showed less than adequate results over all 8 cylinders) and the replacement motor is a 1970 400 sbc (450 horse 548 pound feet) now this truck doubles as my daily and work truck, i tow between 5300-7800 (the 7800 was a 1955 buick special that weighed in at 5800, and my trailer weighs around 2000, stopping that circus was interesting) my question is how to make the truck handle this weight, i've thought about some upgrades that i'd like some feedback on. (1.engine adequate or too much? 2.brakes, would it be possible to retrofit a 1-ton braking system on the truck, and maintain factory ABS? 3.axle 14 bolt SF out of a SRW 1-ton pickup or cab-chassis? 4. rear springs (( open to suggestions)) 5. trans cooler how big and what kind? (( also, should i run an separate electric fan to circulate air through the cooler?)) 6. gears, i'm thinking 4:56s (( i had a 1971 c30 SRW truck with a 350 and a 4 speed with those gears and a posi and it would rip a house down if you wanted it too, i know that because i did...)) and yes, i know i'd have to change the front diff too, so my 4 wheel will work and i wont rip it apart. 7. stall lockup converter WITH a lockup override im thinking a 2300 stall 8. exhaust- i currently have no cat and a flowmaster suv muffler on it with stock manifolds, i am going with headers but my question here, should i go true duals or do a two-into one setup? 9. tires-i run stock 265-75-16 "E" load range tire, should i run something different?, im sorry for the long post but ive read a lot of you guy's stuff and everyone here seems fairly knowledgeable in these trucks. ( Its worth noting my "shop" is a business that builds racecars and does restorations so i know a bit about a bit, but in no way do i consider myself an expert on these trucks) so im looking for any advice you guys have on what ive though about, maybe i missed something? or maybe im too overkill ( which i REALLY dont mind) this is my daily driver but doing what i do, i want something totally different that can take whatever im going to throw at it, again thanks for the help in advance
