Hey, helping my daughter put an early 454 in her 79. Now... what bracket works on this engine for the existing factory power steering pump? 350 coming out. Thanks guys!

 

better front pic I believe.

 

If you have the stock 350 pump bracket, then all you need is a L bracket to align it and allow adjustment for belt tensioning. Might use a couple washers or a spacer on the pivot bolt (can't remember) but that's all.

This one will space it out and allow adjustment too:

1971BB427.... thanks bud! I see the l brackets sold stand alone. This is my first Chevy Big Block build. Really appreciate the knowledge you guys bring. Hope I can repay.

 

pretty sure the big block stuff is the same just have to deal with clearance issues on the gearbox as you will be slightly closer to it second is to recomend to fully weld the front subframe if you have anything over 300 hp the weight and tourque can mis shape your subfram making the steering do crazy stuff when under hard acceleration or you can bend it and be all sorta screwed at the track mid launch

 

SBC and BBC bracketry is NOT the same. Some pieces like alternator and PS brackets will work, but only with another adapter bracket to match the BBC bolt patterns. Chevy used common brackets for these pieces, but different engine mounts to make them work. Chevy didn't do anything different to Camaros with SBC or BBC on the subframes. The only differences were the motor mount height, and the heater cores. Yes, if the BBC is a big HP/torque motor you should consider subframe connectors, but no other mods are needed unless it's crazy HP. I raced mine with a 427 for 16 years and never made any changes to the suspension or frame to stiffen it.
There's plenty of room for headers, and no problems accessing plugs when doing a tune up either. I enjoyed working on the BBC much more than on SBC cars, just because of clearances.

 

greencamaro1981, yeah subframe connectors are already bought, wasn't a problem figuring that part out even though it's a mild build. Gearbox? 1971BB427, my only other concern was headers. We have sidepipes, so are considering these rear dump collectors. I know Hooker Competition has full length that work well but want to keep the sidepipes. My last concern actually was the tall aluminum valve covers we have. Heard they might hit the power brake booster. Thanks guys!

 

Yes, the tall valve covers will definitely not clear a stock booster. You'll need one of the small after market boosters. Might be an issue on the heater box side too. I'm not sure on those shorty headers with angle rear collectors, as you didn't mention the brand. I know Hedman will clear everything with a similar design:
