intersting idea

[01GPGT]

well in the spring i am 70% certine i am selling hte GPGT. i have been wanting a 81-87 G-body ever since my old 82 GP was stolen well here is my idea/ question. has any one put a 60*V6 in a g-body? if so how hard would it be? i fugure i can use a 700R4 from a 80's camaro or early 90's (before OBD2) then use a harness and computer from a GA or simaler 3x00 car and just zero out the transmission section making it think the car is a manual.

any other imput woould be nice just bench racing at this point

for now it would probably be a stock engine going in the car i figure even the 160 HP 3.4L is still better then the 305HO (150-ish) the cars left the factory with lol

the HO305(l69) had 180hp and 240Tq if i remember correctly... if you can make motor mounts, i don't see why you couldn't do it. you're tuning changes don't sound like the most sound way to do it either... for simplicity you could run a 1227727 that way you won't run into tranny issues and have a well documented ECM.

[01GPGT]

never thought of that. is that a OBD1? or OBD2 pcm? i plan on going bigger just want it stock for proof of concept (less bugs to work out and easier to tune)

i will do a search on the PCM though

seems that is is a OBD1 PCM i would really like a OBD2 though becuase i have HPT and a scan guage already

[robertisaar]

stick with obd2 then, but i'm thinking you will have driveability issues if your going to "remove" the tranny code like that.

[01GPGT]

all i would be doing is making it think it is a manual but ya i see what you mean hmm

to bad all the RWD 60* engines where obd1. i will give this some thought i don't want to mess any thing up (wich is why i am asking now before i even have the car)

actually there are 60* RWD motors that are obd2...

the 3.6DOHC comes to mind in both flavors, but i would prefer the 300HP direct injected model...

[01GPGT]

that engines a little to expensive for me lol

and i don't think the harness and PCM would be compatible with a 3.4 (even though i would like a 3400 i know there are starter and block modifications needed)

[no_doz]

yea a 3400 would be FAR superior to the 305 in every area but actual sound (those extra 2 cylinders just sound MEAN, even on a 305...). that trans would work or you could probably just get a different bellhousing, youd also have to relocate the starter to the opposite side of the transmission as well as probably change the fuel pump, but im also not 100% on that one either depending...

youd have to completely wire in the 3400 & a compatible ecm as well, the stock equipment just isnt anywhere near what you are looking for.

[01GPGT]

yup planing on cutting the side of the trans for cleance GM did it in the 80's for there dual pattern bellhousings (b-o-p and chevy) i will most likely got OBD1 with the 7730 force_firebird was telling me abought a ostridge? thing that will let me tune on the fly then burn a chip later

for the fuel i can get a 4.3L TBI tank and a fuel pump assembly from a TPI car. the TPI runs at abought 50psi like most MPI sytems so that s taken care of


but ya the wiring will be fun but it's been done by a few peaple i have actualy found swap harnesses for the 3400. also thinking of just doing a 3500 since they are the same cost at my local yard

[no_doz]

if they are roughly the same cost definitely go for the 3500

[robertisaar]

CANNOT argue with that..

[01GPGT]

there is no roughly it's the exact same price for any engine no matter the miles. it's is highlt amusing lmao

[robertisaar]

don't suppose there are any 90-95 ZR1 vettes there?

i'll take a LT5 for $350. the upper intake alone is worth more than $500, if you could even find one....

at those prices, it wouldn't be a bad idea to look for a 3900....

[01GPGT]

nope no LT5


don't think there are any 3900s eather. but the 3900 would be tricky to get the VVT to work

[robertisaar]

not necessarily, since someone either suggested or did use the shift light output to control the VVT and variable intake...

or you could use the 3500non-VVT intake to deal with that issue.
