this is a super cheap 360 build (or slam together), given the budget i am working with i am not expecting to make a hi-performance build. just a nice driver with some oomph.

recently got a 66 dart with running but tired 273, here is the motor i want to replace it with and my cost on it so far:

- LA 360 from motor home 74K miles - $75
- LA 318 swirl port heads - free from parts car i made $ on

need to get:
- cam
- intake
- oil pump/timing chain/gasket kit/maybe bearings if i feel ambitous

i would like to be in this for around $500 -- any sugguestions?

cheap double roller timing chain. Forgo the pump/bearings so wont have to disturb the pan. SB street dominator intakes can be had for $75 & have 318 ports (matches your heads) and is a spread bore. No opinion on the cam. A FUNCTIONING thermoquad carb

Pan has to come off anyways...to get replaced with a car one from the truck/motorhome one.

Oil pickup tube vent screen should be checked for cleanliness while the pan is off. Low miles means nothing if the oil wasn't changed often enough.

New oil pump is cheap and something I would look at doing as well.

74k on a 360 is still pretty young for just a driver providing it's in good shape. I would be compelled to pull the pan and take a peek inside. I'm just crazy like that.

For sure. Check bearings.

Even though it only has 74k, its worked hard for those miles. How many of them were on flat roads and how many were pulling a grade? Was it used to tow at the same time? Best to pull and look now than to put it together to find out the hard way.

Took a E-58 360 with 110K on it and did a cheap rebuild Troque plate hone cylinders all new freeze plugs and bearings and bushing incl cam bearings. New roller timing chain new oil pump DO not use high vol pump get stock.Comp cam 260 or 268 flat tappet hdy cam cheap and make good power 260 for street every day or 268 with strip time and street. Using a street dom get a good 2"4 hole spacer under a Holley or Carter AVS. Get dist setup with all in By 2200 and get timing up to at least 43+ degree's total no vac. Set of headers and you will have a 14 sec car even in a heavy car as long as you don't have 2.76 gears etc

this looks interesting

I have done this with a few 360 truck engines for towing and 4x4s

last one had the #302 heads with a home pocket port with 1.88/1.60 valves

600 carb
LD4B intake
napa brand cam with .423/.443 lift
headers with duel 2.5 pipes

worked great for a truck, same combo was even more fun in the 68Dart with a stock HS TC and 3.55sg

I say go for it

thanks guys for the feed back now that i think of it i have the 302 swirl heads and a set of the LA360-roller block heads (i forget the casting #).

most of the magic will be upstairs on as far as spending money and making power. good advice on the 3 angle valve job so i will member to have that done when going thru the heads.

i only have a904's that were previously behind a 318, but I can get a weighted flex plate right?

also i plan on using all the engine accessories and valve covers from the 273 so it looks like a stock unit for the car. if possible i would like to use manifolds rather than headers. unfortunately all i have left is a set of 318 manifolds from a 74 dart.

Definitely use those 360 roller block heads you have (should be a casting number ending in 308). Building a low RPM torque motor for a truck I wouldn't hesitate using 302 casting heads on a 360, but for a car it's going to seriously saddled the top end.

Yes you can. I ran one the same piece for years until I stepped up to a 518 transmission.

Don't sweat it, you'll never see a difference between any of the small block manifolds on a mild motor.

thanks for that article!! if that is the case then i am going to use a set of a body 318 manifolds i have and sell the 273 ones.

i can't want to start putting this thing together, now just have to get rid of the parts car and dig out the motor from the back of the shop,

318 ex manifolds wont fit on the dr side ('66 A with SB). You'd need to stay with the 273 logs or 340 HP's work in some cases as there's a tremendous stackup (variation) of tolerances in early A's. In any case the 340 HP's will fit if you shorten the manual steering coupler to 1/2 it length (still works fine). If that's the article claiming only several horse diff between mani's/headers iirc it's a misprint. headers with a good ex are going to be much better difference than that. The 273 logs will fit perfect but utilize a 2" ex pipe. No way that will give you much unless it's going to be a DD stocker
