What you need to do is find a wrecked fbody and get everything from it. Or start looking around the fbody sites. The trans would need the GM hydrolic set up, but reccomend going with the auto 4L60E and a big torque converter, the car WILL be faster this way and it's and easy swap. Trans mount you would have to fab up and the driveshaft would need to be shortened/lenghtned as needed and a new u-joint added to the back, any driveline shop shop be able to do this for you. There are no kits for this so there will be some custom fab work involved.

Yea, you probly will get flamed somewhat, but go to their Conversions and Hybrids section. The guys in their know what theyr doing, i read their posts all the time.

no offense, but if you're hoping to put out 290-295rwhp out of a built 347 with a crapload of money in it... there's a problem right there. most people put that out with an H/C/I 302.

Yep.....I can do that with Nitrous.

for my conversion i know a guy that will make me a standalone harness from a actual harness. then all youll need is 3 wires to fire the LS1 in any chassis. how do you think i did the LS1 in the 240? so for 500 bucks you have a harness that only takes 3 wires and then the rest can be for gauges and etc....very simple plug and play

for the drop out and modified harness about 3000 to about 5000 depending on the combo that includes the trans depending on T56 or 4L60e, accessories and etc. everything you need to do the swap


and for that price you dont really get much of a stang. granted you can make some power then you need a trans that will hold the power then honestly the 302 block isnt that strong so now you got a weak point.

plus its very very very easy to see 30mpg out of a ls1. buddy went 12.8 consistant with nothing more then a SLP SS with my own custom tune with full leather and etc, sway bar connected and got 30mpg with the A/C on.

now you can say you can make a 302 into something strong yes you can. youre not tellin gme nothing i dont know but for the price its not worth it.

now if you wanted to put a joke SBC in it i would laugh but LSX anything is pimp plus you get a motor that doesnt weight much. its about 200lbs lighter then your typical 302 motor

allright!!! everybody put down the wrench!!! ...this just in "it is not worth it to mod your 302!!" everybody go out and get yourself an LSX motor!!.... never mind that a 1500$ H/C/I and 2000$ S/C set-up with 1000$ in supporting mods will get you over 500rwhp, that's just weak and too costly.... get a 5k headache LS1 swap instead and put out 300rwhp!!! it's much better!!!

thank you Quik for showing us the way

Oh great...........(reaches over and puts on the armor) the war is about to begin.....brace yourselves.

Quik

dude dont even start.. if you can make 500rwhp from a 302!! ill reinburse you if you have all reciepts. the key is it has to be NA and last for atleast 5k in miles.

you do know that around mid 4xx the block likes to spilt dont ya?

you have no idea who your talking to and lets not make this a pissing match...im not really in the mood to school ya tonight

SSKiller

Not true. I have seen many setups with 500+ HP on a stock block. Nitrous, NA, and FI cars. The key to not splitting the block is, keeping the rpm's under 6K.

My friends Turboed 342 put out 575 hp at 5800 rpm. It saw many many many track and street passes. Also won the FFFD in Fontana in 2003. What killed that motor was a bent crank. And that was over a year of thrashing it.

Sure the LS1 motor is better. It is about 13 years newer techonolgy and bigger displacement. However I can take my stock 302 and put 500 dollars in it and break off an LS1 anyday of the week with a 17 year old, 120,000 mile, smaller displacement, older technology motor.

HotWheels347

LMAO!! please do "school me" professor... i guess you're not aware that there was an invention called a "girdle" that keeps the block from splitting and many people have seen their 302s last long and strong for years pushing over 500rwhp. but whatever guy, if you're "not in the mood" than thanks for stopping by.
