new from the uk

hi there,
im new to this site and im from the uk, there is quite a good scene in the uk for muscle cars, rods, nostalgia etc and when the weather is good events in the uk are usually great, plenty of cars and racing
im in the process of sorting out a 68 dart originally fitted with a 273ci v8 engine which is long past its sell by date seized and rusted out,
i have bought a 360 engine to put in which is a runner but is on stock parts, havnt found a engine no. on the block (where is it located?) but the casting no. is 3418468-3-360 & 11.22.71, 2bbl cast iron manifold no. 3614645, the heads are casting no. 3418915, the engine also came with a 904 transmission no. 3515852 3553 2097.

can anybody offer me any info on this engine & trans, what it came from? what hp it might have/had? i would be looking to upgrade the cam in it to give it a bit more hp, what is the best cam to fit allowing me to keep the stock heads, valves etc until funds allow a better build also i want to get it on the road next year and do a bit of strip action but keep it streetable

the dart has a 8 3/4 rear with 3.23 gears, the car needs a bit (lot) of work to get it sorted as the previous owner had given up with it and hasnt done anything in over 2 years due to finances, the front end needs rebuilding as it is all in bits - new parts will be needed for this which are quite hard to come by here in the uk, so does anybody have a 67/68/69 dart service or repair manual on pdf they could send to me to help identify the parts required

cheers

george
