My 283 Build

philbilly · 08-29-2012, 05:32 PM

I will just ask all my questions on this thread.

First off I want to thank all you guys that help me. I really like learning. It doesnt look like I am going to be down to long. I already got some ducks in a row with the help from some great people.

Valve ?? will a flat on the bottom valve give me a bit of compression over a dimple style valve?? Whats legal there? Whats angle vlave job?? I have heard of 3 angle but whats the point? Whats legal there?

can use flat or dimple flat will add comp.,but you still have hold the min. cc or more in chamber. any angle is legal,can unshroud chamber to head gasket. can cut bowls to somewhere close to depth of valve guide, BUT this cutting has to be done using valve guide as center using valve guide seat machine. Also cc runners some will check to big out the junkyard.
call me if you want Phil I'm better at talking than typing 606 278 0601

Philbilly Your in good company, pay attention to what Mike has to say. I would get him to do your parts if you are close enough, you wont go wrong ! You can avoid losing another engine.

What is the CC ruling for 283? 50 sound right?

69Cobra · 08-29-2012, 10:41 PM

Looks like the guide shows 54.9 cc's for the combustion chamber if I'm looking at it right.

lifters is the next thing on the list. Whats availble?Is there any way to check mine to see if they are hurt? I know the cam co. has lifters? is there advantage to shubecs or what ever they are ?

Mike Taylor 3601 · 08-30-2012, 02:00 PM

shubeck now smith lifters have diamond hard bottoms (some kind ceramic)on them can run more spring pressure don't have to break-in and can be used on another cam they are somewhere around 750.00 Precision perf. products in NC. have tool steel made for NHRA are around 475.00 can use about 425lbs max spring pressure.
You can check lifters with straight edge hold up to light should see lifter crowned in center if check with dial indicator center needs at least .001 crown in center
If you had bearing trouble cam and lifters could have material embedded and will eat lobes up fast can send in and have refinished and redo the parkerize(the black finish on lobes)
Also Smith's and PPPC lifters have extra travel removed plungers just move .015 mininium allowed
