here's a L head still with the gasket attached, I wonder if you could clean the rust out and take a little JB weld, let cure then take to a shop to have the surface milled down. I'm not 100% sure, just a thought.

Save yourself shit loads of trouble and time, use or borrow a pressure washer to spray all the shit off the engine before you start scrubbing it. After you pressure wash it, it will only take a little bit of cleaning with a scotch brite dish sponge & soap. I've had a few blocks, and cleaned a few. This way works a lot better than spending a shit ton of $ on chemicals to spray on, scrub, wash off, and repeat 5-6 times...

Oven cleaner works also

if your going to fill that hole get it tig welded proper, JB weld in your head is janky :blink:

got the l20b block with flat tops, thank nukeday :D

 

still not sure if im going to bore the block to maybe use ka or even z pistons

or if im going to change the crank,

i need to do some more reading to see what im going for

 

also picked up a w53 peanut head at canby, it needs most of its guts but its still a peanut

only bad thing is i guess i didnt look it over as well as i thought i did.

is that a super bad thing like i think it is or am i ok to use this head still?

 

 

Sorry bud but those are not flat tops

[MicroMachinery]

Look like stock L20b pistons to me.

[skunk]

:unsure: oh, i was told they were........ i guess they do have a bit of a dish now that im looking at them :huh:

well.......

I can get you some 86mm Z car flat tops ;)

[DISLEXICDIME]

better start calculating your compression with stock and flat top pistons using that head

[skunk]

yeah, im going to start working on that. Im having a hard time finding info on the w53 head <_<

i think i might bore the block out to 86m for a z piston and maybe useing a z22 crank.only a 1m bore. Im still in the reading every thing i can find part, and not so much the have any idea what im doing part :P

yea I know, I remember a friend had a mid 70's Ford 4X w/ the 351C, one of the cylinder bore was a little egg shape/ wider in the center of bore so they cleaned it and applied JB with a straight edge, let it set then honed it, reassemabled it and it ran great for years. I was just thinking if it can work on a cylinder bore why not the water passage hole. just a thought. gl

 

 

 

after thinking about this, sounds like what a redneck would do. :rofl:

whats wrong with the l20 in the car?

Stock L20B with flattops and 41cc p nut head is 10.68

Stock L20B ans pistons with p nut head is 8.9

[skunk]

nothing at all, just thought it would be fun to build a cool little L engine.got a free block, cheep head, lots of the parts im thinking on useing are junk yard parts.

+ the engine in the 710 is week, very ugly on the inside.just thought i could drop the l20 out of the 510 into the 710.

that way bother dattsuns get a upgrade and can stay DD.

 

even tho the 510 isnt a DD yet :rolleyes:

what about with stock z pistons and flat top z pistons ??

[skunk]

i got somthing in the mail today :D ill get some pics tomorrow

[nukeday]

:unsure: oh, i was told they were........ i guess they do have a bit of a dish now that im looking at them :huh:

well.......

Told by me. Sorry skunk. I'm about as clueless on the L as anybody on here. I made an assumption, and you know what they say about that... :blush: I thought they were flat top simply because they don't have any sort of eyebrow in them...doh...

[skunk]

its all good, that just gives me a reason to get the block bored and put some z pistons in there lol

[MicroMachinery]

If you're going to DD this thing, I'd really consider doing some homework on the impact flat-tops are going to have on that engine. I was considering putting L18 pistons(Smaller dish) into an L20b, and with a peanut head, I think the CR would have been too high for pump gas. Flat tops with a peanut head is going to give you an engine that will be difficult to run on pump gas.. just some food for thought.

[skunk]

yeah iv been thinking about just using stock z pistons, i would think even the stock z piston would be a good upgrade and i could find them super cheep

[skunk]

got it to fit with the shorter air filters

you can kinda see both of them,

Why does this seem like deja vu...???

Build a long rod 2.1 j/k

 

You would be surprised at how much torque you get just from a stock rebuild .

[skunk]

ill have to look that one up, going to do it now.

SWEET!!! That is an awesome hood scoop!! I love the goast rising sun, and is that "rattosun" on the side??

It goes really well with the rest of ur car!
