LS Engine for my 36 Packard

I am considering an LS engine for my 1936 Jr Packard. Looking really for drive rather than thrust. Couple questions.

1. I see crate engines that offer 2 bolt and 4 bolt mains. Do I really need a 4 bold for this engine?

2. Looking for FI. Do I need to worry about a computer for this?

3. What kind of transmission should I match up with it? Want to try and make this as smooth as possible of an install.

4. Not sure how much modification I will need to do to the front end for this engine?

Really appreciate any thoughts or feedback. New to all of this and looking to learn. Thanks!

You may not need all the smog equipment seeing as your car is so old, but GM's E Rod crate engine can be purchased complete with the computer controls and just about everything else you need to get a fuel injected engine up and running in a different chassis.
Good luck!

E Rod engine

That E Rod engine is impressive. Looks like it only comes in the LS3? I really do not need 400+bph. I am looking closer to 325 and get a little better mileage. I probably should have mentioned I am trying to stay about $8K for engine, trans, and rear end.

For the rear end we are most likely looking at the 9" Ford. So $500-$700 should cover that. Leaving about $7K for the rest.

Yes, that rules out the easiest solution--throwing money at the problem.

Why don't you just pull a 5.3L drivetrain out of a wrecked truck? It seems like a no brainer. You can find them with the engine, harness, computer, and trans for less than $2k. You will also need a fuel pump that can supply the engine. As for mains you must not be looking at LS enignes if they offer "2 bolt or 4 bolt".

BTW, with a good set of headers and a dyno tune you'll have your 325hp, and some pretty outstanding mileage. Thow a cam and a few other tricks in and you can have an easy 400hp with good mileage and still WAY under your 7K budget.

If money were no object... but the joy is finding creative solutions within budgets!

So I guess I go back to all the original questions if anyone has suggestions. Appreciate the leads and giving me items to research.

Thanks for the info ap72. So another newbie question, is an engine set up for a truck going to need to be modified for 'performance' versus 'torque'? I am using the terms loosly.

Also, where does one go to find these wrecks? I Understand there are deals to be had but no clue how to find them? Craigs list has a couple here and there but these things have 160K miles on them and will probably be more trouble than they are worth.

As for the 2 bolt 4 bolt options...I was looking at phoenixengines.com they had a couple different options there.

If phoenixengines lists that then I would NOT buy an engine from phoenix. In regards to the deals, EBAY. Just find one with 100K or less and a reasonable warranty. Those enignes can easily make 300k miles as long as you use good oil, I CANNOT STRESS THE IMPORTANCE OF OIL.

Regarding performance vs torque, do yourself a favor and NEVER mention torque again. It is pretty much meaningless. What you do need to follow is a specific RPM range (where you will be driving) and look for the best power in that range. peak hp and tq values are near useless for a daily driver as they can both occur way outside your operating range if you're not careful. OPERATING RANGE is key when selecting parts.

If you put no other speed parts on the engine you get I would at least get good headers, they make a WORLD of difference in power and mileage.

Thanks so much for the education. This all makes complete sense. Really I am just looking to get something that feels like it has some giddyup when driving not really looking to race it. I will check eBay and I think there are a couple of pull-a-part places around here that might work as well.
