Has anyone used one of the universal cam bearing removal/installation tool? I'm looking at maybe a Lisle LIS18000 or an ATD 8620. They both seem pretty comparable on price $150ish and features. How easy are they to use and get good results?

Which do you think would get better economy on a stock 318? I think in normal driving there would be very little difference. Anyone got any practical experience? The thermoquad would be fitted on a small port Weiand dual plane intake.

I'm stripping down my 360 for a rebuild and will be getting the block hot tanked. I know I need to take out the freeze plugs and oil gallery plugs on the back of the block and I'll be getting new cam bearings fitted. I have two questions: I seem to remember reading somewhere about another...

Anyone using any of the cheap ebay aluminum water pump housings for a big block (CAT, Proform etc) ? If so any comments good or bad? thanks

Anyone got any spring recommendations for this cam? It's 218/228 duration @ 0.050 and .441/.441 lift. It's going in an otherwise basically stock 360 with 308 heads and headers in a '50 Plymouth Suburban with a stick shift. It's a budget build so cheap options are preferred!

Not sure if this is the best place to post this but anyway.. What is the difference between Street Hemi Orange and Race Hemi Orange? Anyone got pics? Also seem to recall that 383s were described as the orange monster in the late 60s. Were there any decals to go with this name or was it...

Any tips on removing these without pulling the intake? I'm trying to remove the driveshaft on a 440 so I can prime the oil pump - it's been sitting for some time. I've managed to lasso it with wire and pull it out about 1.5 inches - enough to disengage it from the oil pump but it won't come out...

I've been offered a 440 out of a 1973 motorhome, is there an easy way to tell if it has a forged crank whilst it's still in the motorhome? Are the motorhome engines the same as used in cars (heads, pistons etc) Thanks
