Sanity check here. lol.
Well a discussion quickly led to an engine deconstruction earlier in my garage with a local member IHA1992 and we tore his factory 283 apart this evening. I looked at the conn rods and found them stamped like it had been apart before. Did the GM plants stamp their conn rod uppers and lowers in house or no? My 292 wasn't stamped so I figured I'd ask you gurus and your wealth of knowledge.

Re: Sanity check here. lol.
The rods were machined and matched but not marked as to where the go. That one has been apart before.

Re: Sanity check here. lol.
That just gives you a good excuse to slap a 572 in there an adapt 283 valve covers on it...that way when you race someone and pop the hood they'll think its a 283.

What heads are you considering putting on that 283? I run 416 heads from a 305 on mine. They definately give it a little more kick.

Re: Sanity check here. lol.
Better off to build a 350 and dress it to look like a 283. Same price at the end of the day, for a lot more HP and torque...

Re: Sanity check here. lol.
This of course is true, but if a 350 was the full answer...why would you want to disguise it as a 283?. To look original? Sometimes it is cool to ACTUALLY run something different, I have no beef against 350 engines, had several and got one on the floor right now. It ran great, but I decided a 292 was more unique and old school looking for the application. To me older obsolete motors are just more fun.

Re: Sanity check here. lol.
416 heads come from the earlier 305 high output motors. They use regular non-center bolt valve covers, have a 58 cc chamber like a 283 needs and 184/150 valves which is a bit larger than 283 power pack heads. They also have hardened valve seats for unleaded gas and assecory bolt bosses. They are still rather plentiful too. I learned about them from the h.a.m.b. but there is a ton of info about them all over the net because 350 budget rodders use them to bump up their compression due to the small chambers.
