can these blocks be bolted for RWD

[alvareracing]

do this motors have side provisions to be mounted straight like in a older Skylark rear wheel drive? Will the tranny bolt pattern accept a 200R4 or equavalent box? Any help would be great.

thanks

Yes they can. trying to finish by Power Tour - Minnesota F-Body Club Any questions on how this went together feel free to give me a buzz 612-708-8015. I used the engine mounts and accessory brackets from a Camaro 3800 V6, as well as the 5 speed.

Wish I knew the guy or where it was posted, but there's a guy that had a Houston shop convert his GP to RWD using GN parts including the motor.

from a series 1 the only thing that can be used in a series 2 motor is the thermostat. 4l60e, from a v6 firebird, 4cly 2.2 s10, will bolt up

mygm, let see if I understand this correct. Series 1 and 2 are totally different (except thermostat) but can either motors ser 1 or 2 be used as a rear wheel drive with a regular tranny (not fwd)?

ser 1 is the motor in the gn 200r4 bolts up, A ser 2 or 3 bolt up to the 4l60e is a rear wheel tranny the one that comes in 3.8L firbird, 2.2L S10, not the 4.3L S10

Do you know if an adaptor plate exist to bolt up a 200-4R to the Series 2 3800 engine?
That would help a little with the swap, you would keep your current trans and not add the cost of a new one (trans) to the price tag.

No, the GN motor is not considered a series I. It it still called just the 3.8 Buick V6. The series I is the front drive 3800 engines from 91-95. The holes on the sides of the block were carried over from the I to the II so the engine mounts will bolt up from the series II 3800 Camaro, Firebird. The only problem with that is the accessory drive setup may present a challenge. The series I has a 1" taller deck height than the series II and as far as the supercharged versions go, the I uses the inner belt to drive the supercharger and the II uses the outer(1st belt in front) to drive the supercharger. Do you want to use an automatic or manual? For an auto you can use the 4L60E or the non electronic 700R4 from a V6 Camaro. The flywheel from a Series II can be used on the Series I, but will have to be rebalanced in order to use a manual tranny.

I think most of your questions will be answered in this thread from on here:

also the vast majority of series 2 engines were coupled to 4t65e and 4t65e-hd trannys

the 4l60e is the trans typically used for rear drive applications of a series 2 3800
