I have 70 318

[Lsp3rd1982]

I want build the 1970 318 into a 355 for boost

I'll do splay caps , half fill it even go as far running reverse cooling heads like 95 lt1s.

My question what heads are best for boost and do they make aluminum ones?
Going efi and running e85 on this boy with the holley terminator will be my plan

 

[Chryco Psycho]

W2 / W5 heads would be my pick , eddy is a waste of $$

Why the stock 318 ?

Why the stock 318 ?

Because I do my own machine work already have the block and its orginal to the car so no reason to change out blocks. just update billet main caps, half fill arp rod bolts should hold up well.. I mean if 1995 Gm lt1s people are getting 1800 hp out of modified 350 I would like to believe that original 1970 318 would be more stout of block

I never liked edlebrock heads... do you know if anyone has them aluminum

The crank is forged,right?

Will be ls crowd are using molnar stuff for 2000 hp... and they do offer forged cranks and rods for small block la engines so believe I'm going that route

 

[340challconvert]

1970 318 should have a forged crank, though there is controversary as to when the transition from forged to cast took place.

The early forged stock Mopar 318 crank is actually a pretty good piece and is good for at least 6500 rpm. From what you said,I'm going to venture to say : You have done Machine work included boring and honing with torque plates line honing the main bearing saddles, and decking the block Molnar is a flat plane crank or cross plan ?And smaller crankshaft rod journal.I've done machine work a few years. Only paid so much,I moved on. You know what I'm talking about when you can feel 1-2 thousands on a valve stem. you don't need a mic. bear with me I'm still on the bottom end of this. magna flux rod and main bolts?

Just have the block and period correct heads they were in the trunk If it was forged someone swiped it long ago

 

[moparleo]

Can't wait to see the build up.

 

[Lsp3rd1982]

Can't wait to see the build up.

It's going be fun one when done, I see a lot of guys chasing big blocks even my uncle spent a lot on 540 with blower for his super bee .... me I'm going 355 and let's hope it can hold ,I think it will... the 70 challenger will be done by November ..

Can't wait to see the build up.

Definitely, cant skimp on testing the structure the main bolts will be arp .. block will be o ring.... I was even thinking about sending block to be cryofreezing it but I believe that's more myth than anything else

 

[Challenger RTA]

I was wondering about O ring? + The block has been
therm o cycled over the year. So it's been stressed relived. cryofreezing: The science is it stiffer and harder. Do want that ? depends on what! My opinion. Screws break and nails bend.depends on the hardness. You want he wearig parts to wear,rings bearing.there is harmonic flexing and at what speed? if you are going 10k rpms and beyond,as formula 1 or others do for long periods of time,Then maybe. When looking to the future look at the past and see what works. If any thing I would sonic check the cylinder walls.you probably already done.
