yeah I know. got one of the last ones he built. I guess step one at this point is trying to decide which engine/trans options to go with.

skip the rear mount turbo. where are you going to put it? if it ends up by the axle, screw it, waste of time, its going to lag like a mug. if you delete ABS there is a ton of room under the hood to do a front mount. otherwise a tvs 1900 will get you in the 500rwhp range or go 2300 and set your sights higher

Well i've starting looking for a motor and i've been researching some and i'm wondering if the 6sp Auto transmissions out of the Silverado 1500's will fit in the Impala's without major modification.

thought i'd share a pic, haven't seen anyone run gen5 Camaro accessories

the stock alternator pulley is pretty large, replaced it with one off of a truck alt I had laying around. also had to massage the steering gear for clearance. and lastly, move the abs box over about 1" (note the mount on the gear box) to clear the ps pump





I have a question, what do people do about coupling radiator hoses? the only thing I could find locally are nylon couplers at home depot, do you think they will be ok at operating temp?

Jimmy, to couple the radiator hoses, I used an aluminum adapter from jagsthatrun. Mine has a port for the steam line, and a bleeder valve on it to assist with getting rid of air. I'll look and see what hose I used, as we are using the same water pump and PS pump setup. IIRC I just bought a new Lower hose for the Lt1 Impala SS and used it for the top connection.

You can see the adapter in the photo above the oil filter (in the radiator hose of course).

Excellent forum…….
I have learned so much, thank you.
I’ve read through a lot of posts and unless I’ve missed something, will the conversion pass a NY State Inspection?

do you mind feeding my curiosity? it seems like you've connected the steam line to the nipple on the coolant reservoir, using a T, is the other side of the T capped?

There is no T in that photo, it was run straight to the coolant reservoir. I switched it to a T in the new setup as there isn't anywhere on my factory radiator to run it.
