If you have an older 350 block and want to make a roller block out of it, do you need to modify it? Question 2 would be, if you have a roller block, can u make it work if you dont have computer wiring in your vehicle? Question 3 is... If you had a 350 bored 30 over and stuck a 400 crank in it i beleive you would have a 383 motor. now. if you offset grind .025 off the crank, what do you have at that point? Last question is...If you dont intend to drive it too hard, would it be safe to grind the crank?  Thanks Stan In NE Pa.

1. no, just buy a retrofit roller cam kit

2. yes, unless you want fuel injection

3. 385 but why not just buy a 3.800 stroke crank & get 388...the 385 can be had w/.040 bore & 3.75 stroke

4. yes but why not just buy a crank of the desired stroke

Thanks Scotty for your reply, I guess then that the best thing to do is just get a roller block and rebuild it. If a part in the retrofit package went bad, it might be hard to find a replacement. ( just a thought ) As far as the crank goes, i see your point. I'll be starting a project in May, and i'm trying to get my ducks lined up. So far i have a 350, 400, 454 and a 500 cadilac as a candidate to put in my 50 Plymouth Coupe. Lots of time on my hands, im not in the USA right now, until May. Lots of thoughts and adrenalin flow going on here. Thanks again Stan in NE Pa. (but right now in Honduras)

The retro-fit cam kit includes roller lifters designed to fit older blocks, replacement parts are available from the cam manufacturer.

If you have a 500 Cad waiting for attention...USE IT

  I just want to add my 2 cents worth. As you know by now
how expensive Hydraulic Roller Cam set-ups are. Be carefull
not to Over Cam your engine.Same rules apply. The Cam Makers are doing
so much with Cam Technology today that (Bigger is not always Better).
  Make sure you use all the selected CAMponents..lol.. the cam maker
suggests. Use a ( CLOYES TRUE ROLLER timing chain set-up also). Don't
forget to use a Roller Cam Button. Roller cams be-it Hydraulic, Solid,
Rollers, tend to walk in the block. It can lead to excessive Cam Gear
Wear. Even when using the correct Distributor Gear....Also make sure
your rear Cam Plug is not installed TOO-Far inward. I usually install
that Cam Plug after I have Mocked the engine up a few times.
  In fact a Poster had a problem (He couldn't install the oil pump
driveshaft). That was actually the caused by the camshaft being pushed
too far to the rear of the engine. It's these problems that really need
to be addressed, and kept in the back of ones mind. But we are here, and
there are some smatr guys in the Forum. keep us up to date as your build
progresses. Good Luck....

Did the P/U have any ECM problems before it was put away? That's the question I'd want answered. Sometime the old system can surprise you and work.
  Testing the OBD-1 ECM is easy and inexpensive today do to the OBD-2. You can pick up a diagnostic tool for OBD-1 at any NAPA, Advanced Auto, et-cetera. It's very easy to use. Instructions should be with the diag. tool. One thing make sure your battery is charged with at least 12.7 VDC. You can leave a charger on it as your doing the testing.
