Not sure about a Lemans, but I had a 71 Olds 442 and spent some time playing with it. To be clearer, I spent $23,000 restoring it after spending about five years trying out different cams, rearend gears, and going from a Muncie four speed to a T400 tranny. (I never did remove the clutch pedal because I figured I might go back someday)
Anyway, if you wanna leave it stock great. If not get a new intake and put a 4 barrel on it. If you are looking for good driveability get something in the high 300 as far as the rear gear ratio. I had a 410 in my Olds for a few weeks and decided it was fun as hell from stop light to stop light, but for a highway drive it SUCKED. I ended up with a 370 ratio and a Moroso Brute Strength Posi carrier, in my GM 10 Bolt. (The guy before me blew his rear end and decided to sell it instead of rebuilding it, what a JACKASS. I never found a reasonably priced 12 bolt over the 16 years I owned the car)
Anyway, I don't know if that helps, but I got my parts from Summit Racing and NEVER had a problem dealing with them. I rebuilt the engine three times with parts from them and would order from them again.
If yo ureally feel crazy and don't want a crate motor, go by some old beater and steal the engine and trans from it. For example mine was a 71 with a 350 and a 4 speed in it. I bought a rusted out 1968 Olds 98 that had sat in a farm field for years. I only wanted the engine and trans for rebuild. The 68 98 came with a Olds 455 that put out 365HP and 510TQ and had the Olds "C" heads I was looking for. That was also where I got the T400 tranny. I junked the car after canibalizing it. I had the block machined and the heads done and put a mild build on the engine with a nice streetable Comp Cam. Loved the car once all was done, so I did a frame off restoration (the $23,000) and loved it more.
Took it to the track once and ran 12.7's with street tires spinning through second gear and the exhaust still bolted on it. I only sold it because I needed the down payment for my new house I bought a year ago.
The selling of that car brought me to the purchase of this one. Go figure, I missed the power under my foot.
