Can anyone give me an idea of what crate engine (small block) will drop in my '72. The motor isn't original.

All of them?

Any GM small block is going to have the same mounting locations. The only thing I can think of to look out for is a provision for mechanical fuel pump. And any motor with Vortec heads will require a new intake manifold.

Are you looking at a long block, or a more complete carb to pan package?

Thousands of options. Need to know rear gear ratio, trans, power expectations, intended use, what is important to you? fuel mileage, HP, Low end torque, Are you drag racing, want a highway cruiser, planning on drivetrain upgrades, overdrive trans, lower rear gear? What is your budget? No one can answer your question without answers to all of these questions. You can buy a stock type 200 hp replacement for about $2000. You can buy a 600 HP fuel injected forged engine for $15,000. Heck, a 700 HP. 540 big block will swap in with a minimum of modifications but once you pass 450 HP or so you need to look at some drivetrain upgrades that add up fast. All of the above are the perfect crate engine for someone and will drop right in your car.

Thanks for the replies. I guess your right, I need to decide what I really need/want. I just figured I would stay with small block, possibly a 383??

I agree with 63Mako there is lots you can do, but we need more info to help you out. I'm thinking of a 383 myself and JEGS is making them very affordable. Figure out what you want your new power plant to do. let these guys know, and you will get some great insight. Good luck.

Knowing your target HP and budget are really important. I am also trying to put the pieces of the puzzle together for my rebuild that started as a just drop a crate motor in. The crate motors are not like a rebuild, you have to like the components offered in that package. The engine could just be the starting point. What transmission and gears do you have? The knowledgeable people on the forum need to know in order to help.

Agree with the above, but you'll also need to get a flywheel/flexplate if you get a 1-pc rear main seal block as the crank flange is different.

My advice would be a ZZ4 , it is not the most powerful , but for the price and the 355hp , 405tq ,, your getting a brand new engine with a good warranty that makes sense. If your budget is unlimited I still say go crate just chose a stroker motor .

Like stated above you have to first figure out what you want. There are thousands of options but if you get a crate engine stay away from flea bay. Summit or Jegs or Gm are your best bet. You still have to pay for shipping if something goes wrong and most of the time they will blame it on you.


You might want to find a good local engine builder. Go to a dragstrip near you and ask around. If one name keeps popping up then go talk to them.

Quality builds are not cheap but better than fighting with some crate engine builder 1000 miles away who put claimer pistons in your motor. I always tell people to get one built within sharp stick poking distance from your home

I second the ZZ4. I love mine compaired to my L-79 327. A lot of low end torque and it reves like my L-79 did to 6,000 rpm.

Default Gmpp zz383

I bought a GMPP ZZ383 for my 80...I also installed a new GMPP water pump, distributor, fuel pump, an edelbrock intake, edelbrock carb, & nos 2.5'' genuine GM exhaust manifolds. I'm using the stock air cleaner assembly. I also installed a 2200 - 2500 rpm stall converter. The engine runs so nice & has tons of low end tourque...So, if your're thinking a 383, the GMPP ZZ383 may be a great choice...good luck.

I'll be looking for a motor with more power in the next year for my 72. The original runs fine, but I want more power, so I'll plan to put it on a stand. I'd like to get something with 350-400 horse and has plenty of torque for street use. My car is a 4 speed with std rearend gearing. I have to admit I just want to melt the tires and street race a bit and stop backing down to souped up Dodge Neons. I'd appreciate a recommendation. The GM zz4 engine is a bit pricey at $4400.

I'd love to hear the details that you're working throught to get your crate motor to work out. I just chatted online with a tech at Summitt and they're telling me that the 1 pc rear main seal and crank flange should mate up no issue. So now I have no idea what to think, other than I should take the advice in the string and buy from someone local. Anyway I appreciate anyones thoughts. Certainly not trying to highjack the string, just thought the questions are identical and we can both learn from everyone.

Thanks
Dan
