283 build questions

Started assembly of my 283 rebuild. Heads are reworked power pack heads, shaved .005, bore +.060, flat top pistons with valve reliefs, Edlebrock 2102 cam.

Would there be a problem running CramCams stamped roller rockers 1:5 and no valve guides? Push rod slots are small.

Compression issues with pump gas?

The damper was a small flat pulley mount with no thick damper ring.
Not sure is this is a cludge job on the damper. I have a 327 three spoke damper. Will it work?

Where is the temperature sensor?? There was nothing in the heads or the block and don't see a hole for it..

Streets,
Books were not much help. Nothing I didn't already know. Used to know more, but now old enough to forget. Maybe you will get there some day.

csf03716 ,

Thanks, sure send some pics. Did you replace the body to frame rubber mounts? Makes a big difference.
The temp sensor was not there cause the numbers on the intake indicate it has been replaced with a vette cast iron q-jet intake. This will have to go. Putting on an edelbrock.

that is a crossfire intake.....you may want to reconsider swaping it out.

I have a set of Power Pack heads in the shop. My machinest tells me they need hardened seats. Running old heads with unleaded gas is problematic. The lead acted as a valve lubricant. Take away the lubricant and the valves eat their way into the soft cast iron. The fix is hardened seats. He quoted $30 each or $480 for the job. You can get a set of street replacement heads that flow better for that kind of money.

If anyone wants my Power Pack heads I'll take $100 for the pair.

Had the heads redone with hardened seats and new valves , keepers, and springs for 230. (East Coast)

Also have another iron intake with the egr stuff blocked off.
Will double ck the numbers on both.

The 283 is cool but gotta say inches are even better. The only exception for meis the sweet sound of a SB's instant RPM wind up. The problem with all the high RPM stuff is the parts needed to live there and what it hurts when they let go at 8000 RPM. The money it takes to support the short stroke/high RPM is spendy. Meet some middle ground and go with 327 --- you get forged crank and rods and little more inches but still buzzes up especially injected like few others. a 302 build is also pretty nice and only pistons are needed to make the combo work. Have fun with your build it sounds like you are going to have a screamer.

The car came with a 283 so yea, Ill stay with it. Wake it up a bit, its a cruiser or parts getter. Rebuild keeps me busy and then look for a project ol skool rod. One project at a time.

csf03716, did you send any pics?

ANyone used a two piece timing cover? Now the water pump wont clear the cover.

Beware, problem with the 2 piece timing cover is the fit. Called Mr Gasket and sure enough there is a QC probelm and I was told to take it back to the store and they have had complaints. problem is it was a gift. Junked it and went with the stock.

you may want to have your machine shop tap the crank and get a streetdamnpner or fluiddamnpner depends on the radical-ness.........scooter p.s i have a 283 bored .125 over is fine on the street 12:5-1 compression no issues and yes i do have msd 6-al with a pro billet distributor....my 2 cents lol...............scooter <again>

Early small blocks up to about 69 used the short legged water pump. Most 2 piece or cast timing covers need a long water pump for clearance. I just used a chrome steel one on my currant 355 engine project for the '69 truck and had to grind off a little of the lip on the stamped cover on the back of the water pump to get it to fit. The reason I stayed with the short pump was that all of the other pullys and p/s and alt mounts that came with this basketcase project were for a short pump.

Stayed with the short pump and stock cover. Simpler to avoid the pulleys and p/s headaches.
Lets see. I have a picture around here somewhere.

Currently running a Q-Jet. Anyone tried an Edelbrock carb?
Heard they are easier to tune.

its my expierience that every edelbrock ive seen leaks. q jets work better then edelbrocks but holley is best. just my opinion :toocool: ...................scooter

yes but improvements can be made.....................scooter ALOT of improvements

. . . anything and everything produced by the factory will out last and out proform any aftermarket hype bullsh8t piece...period...

Then I guess Crower, Edelbrock, Keith Black, Milodon, ARP, Ross, Crane, Dedenbear, Pete Jackson, TCI, Manley, JE, Hooker, Dart, Brodix, Barry Grant, MSD, Mallory, Wilwood, Lokar, Super Bell, Richmond, B&M, Moroso, and a few other should just shut down.

Whatever you're drinking, Charlie, send me some . . . :LOL:

i agree with your henry lmao that must be some good shit :LOL: :LOL: i mean factory stuff really doesnt last THAT long .....scooter

I did not realize there were that many 64 ss owners in Club Hot Rod. I had a 64 impala ss 327 250 h.p. 4 speed 40 years ago. yellow. At the time I would like to have had a red 300 4 speed.A couple of years ago i found the car with the build sheet in the car. the 327 was gone and a worn out350 was in its place. No carb. no dist. and all 4 brakes were lockedup . I paid more for the car than I paid for in Jan, 1965. A friend of mine has the matching numbers short block, built two months to the day prior to the build date on the car. That date is perfect. bored 030 plate honed .forged flat top pistons, comp cam. cloyes double roller timing set.Sinclair Impala parts, Danville Va. is where i am buying my restoration parts . they tell me going original with a 64 is not going to have any more value. They have a 59Impala on the cover of their catalogue. The owner there says he went to a lot of expense to do the original 283 and has since wished he had put a new crate motor in it. Ihave a355 race motor that we built for stock car racing over 15 years ago that I never used . Also have a new set of Brodix track 1 heads that Ive had for years and never used .They think the car will have more appealwith that motor.

I have bought parts from Sinclair and they seem to have most anything and ship quick.
It is the original 283, but the main reason I used it is I had a 2yr old 64 SS right after HS with a 283. Its a daily driver anyway.
Cant stand those foreign cars that sound like a fart going down the road. Ya might get a few hp numbers out of them, but no torgue. Foreign is just wrong.

in: finishing all but putting on the intake.
out: dropping a bolt down the lifter valley drain hole.@%**$#@
out: removing oil pan to remove bolt (after beer buzz is gone).
in: its back together again.

That's all a 302 is - a 283 bored +.125" (4" bore, 3" stroke).

well my motor bored .125 comes to exactly 301.6 the 1st 302's were 327 blocks with 283 cranks then in 69 they made 302 blocks but only!! in 69............scooter

A 302 in 1967 used a small journal 2 bolt block. In 1968 all small blocks went to large journal cranks During 1968 and 1969 they based the 302 on a 327 large journal with 4 bolt mains. they used 3 different cast #s on those blocks in 68 & 69. These motors were built for chevrolet to compete in the Grand American series of Nascar and to my knowledge were available only in camaro ,however , somewhere in the back of my mind I think it might have been an option in a corvette one year.

dont you mean the trans am series where the cubic inch limit was 305.

Could be! I thought about that when I said it.You are proberly right.Remember going to the Paul Revere 250 under the lights at Daytona in 1969. I remember the cars for that race were equipped with lights.
