motor swap

[292farmer]

ok so i want to pull out the 292 in my truck so i can rebluid it and want to install another motor in it to keep it running and useable. i havent found another inline that runs the only one i found locally in my area was pulled out of a truck 15yrs ago and was stored in a jeep wagon, and the guy wants 500-600$ firm...so out of the question for me.how ever i found a 305 v6 and a 283 v8 the 305 is from a 61 gmc and the 283 is from a 57 chevy truck, both run and are both 500 obo
so i know the right side passenger mount is moved forward on my 292, but will i be able to use the drivers side or will i need all new mounts? which would bolt in easier? i have the sm465 my truck is a 3/4ton so im not sure weight on 292 but i know the 305 is about 650lbs so i might sink a little? would either one bolt to my bellhousing with out requiring movement/replacement of my tranny or use of an adapter?
i believe the 283 shares the 292 bolt pattern but im unsure and idk about the 305. both were hooked to manual trannys before. also the both motor came with trannys if i want should i do that? both are 4 spd so im guessing their the sm420? would that make my job easier?
sorry this is so long i searched threads but whilei found mention of swaps from v6 to v8 and vice versathey all included tranny swaps, which doesnt help much with my idea of bolting to same tranny. any advice please thanks

I think you will have an easier time with the 283, you will need new mounts and the 305 v6 mounts are no longer made (along with a bunch of other 305 v6 parts). The bellhousing for the 305 v6 is also hard to find...with the 283 you should have a much easier time mating the transmission up and finding mounts.

be carful with swaping for the v8... you might fall in love w/ it and ditch the six!

thanks dccarpenter, after i asked u guys i remember my dad had the blown 305v6 still from our c60(we dropped a 401v6in its place)im going to check the motor and see if it has a bellhousing, cuz i thought the 401 came with one. now if i can just find it in the garage....
and the 283 sounds like a cool little motor. ive heard the 283 are really tough and hard to kill, whats the story behind that?
lol dont worry about that me and my buddies were talking last night they lay claim to what ever motor i drop for next years project. this year we're building a baja bug.last year was getting the "redneck hummer" fixed and running. so i cant keep the motor even if i like it, besides i traded a 1986 350v8 truck for this 292, im determined to have this 6!

My vote is go with the 305 V-6. The torque and horsepower are very similar to the 292 I-6 and the cool factor is off the charts!! You will have to use a V-6 bellhousing because they are different than I-6/V-8 bellhousings. Also, you MUST use the flywheel from a V-6 on a V-6 because it is used to balance the engine,(there is no harmonic balancer).

ok im pretty sure i talked to the guy it comes with flywheel and bellhousing now im just trying to see if i can locate motor mounts
