what sould i go for.i want a torqe monster.and im looking at a 318or360 because i can get them really cheap and easy.that and the mods i have on my 318 i could just put on my stroker

Use the 60 block if you have a choice of blocks, and i wouldn't use anything from the 18 on a stroker totally different motor once you add that crank and it wants alot of things differently

will i be able to use my intake?its a wiand action plus dule plane

 

[Evildriver-3]

You could but it will hold the motor back, you want much larger ports on a stroker, keep in mind if you go to a 4" crank motor you aren't building a sb in the sense of what you're used to, you are building a motor that is a big block with heavy fast breathing.

sweet.im planing on doing this build up over a long time and do it all right

maybe a factory type or mild intake will work. it will be short on breath on upper rpm, but if you are trying to build a motor that purrs at 500rpm and never sees more than 3000 or something, maybe mild parts will work.

 

[Evildriver-3]

No actually that stroker likes big ports and high flowing intakes and heads.

ED-3 is right, the larger ports are what you want for a stroker 360.

ED-3 is right, the larger ports are what you want for a stroker 360.

like i said, depends on the intended application. what if i did not like the power band of the stock 360? what if i wanted even more low end toque? maybe for a rock crawler or something. then i would continue to use stock type parts with increased cubic inches. if i upgraded the parts and increased cubic inches, powerband would stay closer to that before. there would be more power still closer to oem. on the other hand if i went even more aggressive, the power band could be rose to more high rpm street or mud bog performance.

EDIT:
i reread the orignial post stating he wants a torque monster. he allready has some slight modded parts for his 318 such as the weind intake.

since he allready has this stuff, he might as well try it out. might just be the ticket or it might suck ass. then he can step up to more aggressive cam or mopar m1 single plane or what ever.

If you wanted to just increase your low end, you would not use 18 ports on a stroker, in fact you could use W heads and make monster torque down real low, this isn't a regular 18 or 60 to many things have changed and by using little ports you would hurt your low end performance, only problem with W heads is the exhaust situation becoming very expensive

if that was the case, 360 should have more aggressive parts than 340s, so they can make more torque since they have a larger stroke and now its a totally different engine ?

lol, a real increase in torque could be found with a pair of garret t3s with .63 exhaust housing.

 

[Evildriver-3]

Actually a 360 is different than a 340 a 40 is a 18 made to work high in the rpm band so a bigger bore is needed for flow upstairs take a 60 and a 40 and build them using the same everything other than strokes and pistons and the 60 will make more lower, add a 4" crank to a sb and you have now made it want more than a bigblock and it will breath more than a big block since now the rod ratio has been changed and it will want to move more air even at low rpm since the piston is moving much faster and it can run more cam without hurting lowend

 

[Evildriver-3]

Im not saying it won't make alot more torque and hp with 18 stuff, but it can make alot more of everything easily by using large ports

 

[s ǝoɾ]

true.

i still think should start with what ya got for a baseline. then worry about w2 ebrock ect ect

 

[Evildriver-3]

No if you do that you built the motor for a 18 head big chamber, now going to a W or say edel (alum is also a problem) is a problem since chambers are different.
Playing with a dual and open intake ok but heads will mean changing to much in how the motor works with everything else
