can you replace a 4th gen camaro’s v6 engine with a small block 383 chevy 450hp engine?

You should be able to, people drop in 350′s in there all the time. You will however need some new bracing and suspension upgrades to handle the added power.

that cars stock tranny will not last long in that setup if it will even bolt up. i believe the only gm v6 with the correct bellhouseing bolt setup is the 4.3v6 so any other v6 will require a diferent tranny. plus you will have to go to stiffer front springs to handle the extra weight. also probably better brakes to stop the extra power.

better have a pocket full of cash because everything will pretty much have to be changed! transmission, drive shaft , radiator and cross member will all have to be changed to make this engine work. sorry for the bad news!

yes you can ,any camaro made can have a v-8 installed in it,those are easy ones to do ,but there is some changing to do,you,ll need a transmission up grade,along with a rear differential also,but yes any of them you can install a good v-8 in,good luck with it.

The transmission will need to changed out with the engine. Your biggest problem will be what you do with the onboard computer. It can be upgraded for use with the 383, or if you go with a standard carburetor, you will have to remove the factory fuel pump for the EFI. Physically placing the engine in the bay is fairly straightforward.

Q: Does it pay to swap my 4 or 6 cylinder engine for an 8 cylinder?

A: First of all, you have to decide if you are going to keep the computer system. It’s a bigger hassle if you do. Your best bet is to go to a junkyard or find someone who is parting out a V8 Camaro/Firebird, and pull as many parts as possible off the same car. You will need brackets (i.e. alternator, AC, smog pump, and power steering pump – save the bolts too), AC hoses, and Pulleys. You will also need new rubber motor mounts (about $20 at local parts store) and the engine side brackets that these mounts bolt to. Make sure you get the engine side motor mount brackets from a Camaro or Firebird as they are a little shallower and are needed to get the engine to sit low enough in the bay. The holes for the motor mounts are already in your crossmember. You will also need to get the engine fan and fan shroud (junkyard or new – your choice). You will need to buy a starter, water pump, and probably a power steering pump (get thses from a junkyard as they’re almost always still good). You’ll need a V8 HEI distributor. An ACCEL rebuilt HEI works great and costs less than $150.00. And of course plugs and wires. Assuming an automatic tranny, you will need a new tranny since the bellhousing bolt pattern is different on the V8 car from the 4 and 6 cylinders. A Turbo 350 will bolt right in with B&M’s $75.00 conversion kit. It just lets you hook up the torque arm, but you’ll lose overdrive. Take a polaroid camera to the junkyard, and you should be able to figure all this stuff out. Finally, you will probably have to change the front coil springs. I know this sounds like a ton of work (especially since it doesn’t even include what you have to buy to assemble the engine), but this swap is really a piece of cake – everything drops in like it was supposed to be there. At the very least, assemble all the components you’ll need (build the motor on an engine stand over a few months with all accessories and brackets), and have someone drop it in for you. A shop would charge you an arm and a leg if they had to scrounge all this stuff up themselves.
