Ok im a body man and pretty well clueless about what goes with what on building a motor so any help would be great. I have a 1970 c/10 with a stock 350 3 speed transmission (3 on the tree) 2 wheel drive. Its got a bad knock most likely a spun bearing so I gotta tear the motor apart so while its apart I wanna build... well what I call a cruise motor. Fun to drive grabs everyones attention and the sound of it pulling up to a show or on a cruise night sticks in your mind.
The only motor mods are headman hedders and an edelbrock 600 cfm performer series carburater (part # 1405). I want to put a Comp Cam Thumpr cam kit in this motor, the kit number is gk12-600-8. It comes with Hydraulic Roller Lifters and a Gear Drive Timing System. The cam is a 283THR7 = Duartion 283/303 Duration @.050 227/241 Valve Lift .513/.498 Lobe Lift .3420/.3320 Other than changing springs and installing a thrust button (whatever that is) what else is going to need to be changed I would like to keep the rest of the drive train stock as much as possible. Any opinion would be greatly appreciated this truck is my baby and i just want to build it right

Re: Building my first motor
i'd recommend moving this to the engine and drivetrain section......more likely to get a lot of responses there

Re: Building my first motor

Re: Building my first motor
Well for one thing with that roller camshaft you're gonna need some better valve springs. Whatever the specs that come with your cam should give you an idea what you should use.
Good luck!

Re: Building my first motor
That's good advice about getting the book before starting your project. The cam you've chosen is pretty big, and IMHO, too much cam for an otherwise stock truck slated to cruising duty. If you wanted to keep it simple, I would recommend a 262 Voodoo hydraulic flat tappet cam/lifter kit. I installed one in a buddies 327 Vette. It sounds nasty at idle, and really woke the engine up, compared to the old Cam Dynamics cam it replaced. The 262 will offer a healthy idle, good vacuum, and excellent throttle response. It will also be easier to tune and keep tuned, which will add to the enjoyment factor. Just my $.02

Re: Building my first motor
I would recommend using your current carb and headers and doing this,
9.5:1 compression vortec heads, screw in studs, 1.5 roller rockers comp cams XE 268 hydraulic flat tappet cam edelbrock performer intake HEI This should make a great daily driver combo with power peaking from 5000-5500, and you should have plenty of torque, probably close to 400 ft lbs. The thumper cams sound great, but you'll need a higher static compression ratio to run it and a better head to take advantage of the increased valve lift.

Re: Building my first motor
First of all you should take the block and crank to the machinist and have them looked over. The mains most likely can be line bored but the crank could be to far gone. If every thing checks out, follow through with your build. I would go with the vortec heads like 67ss said. They breath so much better. Plus they are pleantyful and most likely can be found at a decent salvage yard at a better price than having you 70 heads worked.

I agree with the above posters get a book, do it right, have fun, and if you store it seal it up good (I didn't and I had to rebuild it a second time since water got in it!). good luck

Re: Building my first motor
I would recommend this book...
![]() ( It's a metal washer that you weld on to the timing cover to keep the cam from walking bty.) With this book and a good machine shop I had a successful build. It has detailed info and plenty of pics. Also if your going with a hipo motor then pickup a copy of ![]()

Re: Building my first motor
That's is a good book to start with. The autozone in my area sells that book. You might check that out if you don't want to buy it online. I can get you the part # for it.

I just did a search for thrust button on goggle and realized techonolgy has changed. Thrust buttons with needle bearings wow. And yes back in the day on flat tappet motors we welded a washer from the hardware store to the timing cover for cam walk. But my bad thoes thrust buttons don't require welding. Sorry for the scare rew338. Also I just noticed your talking about a roller motor and I was thinking flat tappet.
