so did you and 440 miss the part where the OP says he plans to put EFI on it in the future when funds allow or did you discount that or are the mods he plans to do also a waste of $$$!! with EFI ?Fast Eddie wrote:I don't disagree with you on the original poster, replacing with a stock 360 2 bbl?? I would not bother with ANY of the above mods. No gains for your $$$!!

I have 2 sets of headers for an AMC 360.
My recommendation would be Doug Thorley headers
Whatever you do get, get ceramic coated. or buy plain ones and send them off for ceramic coating. it will help drop engine bay temperatures.
I attached some photos but I didn't take them to show off their features so they aren't the best but may help.
Hooker Competition Headers: The quality is so-so. The flange is 1/2 the thickness of the Doug Thorley.
Doug Thorley headers are much higher quality. thicker flange, better material in the tubes. If your budget allows, get the Thorley's . if not, get the Hookers but then get them ceramic coated.

thanx Ed! that's exactly what I needed.Fast Eddie wrote:Rinkle,
Sorry did NOT catch your idea of EFI down the road. I agree with your rebuild ideas for the NEW motor, lots of cams available, I have one that is rated for 1500-5500 RPM, might of gone one step smaller "IF" I did it, but this was all done by PO to my truck. Comp Cams high Energy 268H Daily driven and slightly rough Idle Part #10-202-4. I have the Edelbrock intake and the Edelbrock 600 cfm carb. My J20 truck was a 360 4bbl from factory...!!! Hope this helps a bit and good luck on your project.

I believe you’re still missing the fact I’m going to do this in stages...including exhaust. My goal is to tackle mods to the engine while it’s out (without completely rebuilding the engine from the ground up) and add things later while it’s in and exhaust is totally doable while it’s in... I have a budget I have to stick to.440sixpack wrote:EFI ? OMG , better add street slicks on all 4 then.
EFI without compression may run better but it will still be a gutless wonder.
People really need to be realistic when they consider performance upgrades . what works at WOT drag racing isn't what works best on a dirt road with a 4x4 or your wife running for groceries at the store. bolting on a few additions to an 8.2 to 1 360 is like lipstick on a pig. maybe you think it looks better but it's a waste of time.
Factory 401's in 1971 put out more power than 99% of Jeeps on this forum and they did it with a 4v and cast exhaust and intake manifolds. AND COMPRESSION . Hemi's, 6 packs, 421's, 428 cobra Jets , 429 Boss , stage 3 455's and a bunch more developed more power and torque than probably any Jeep on this forum and they did it with cubes, carbs and cast exhaust manifolds. AND COMPRESSION .
I'm not trying to be a downer or a smart azz but lets not encourage people to waste time and money for nothing . if they know what to expect and still do it then by all means go for it it's your rig knock yourself out. but after all that and a Kia still eats your lunch don't say you weren't warned.
At no point did any of us suggest that EFI was going to give huge power. We stated that he was keeping the 2v carb for now because there was no need to waste money on a 4v carb when he was going to EFI.440sixpack wrote:EFI ? OMG , better add street slicks on all 4 then.

Speaking from experience, of modding my own FSJ's, both V8's and i6's, those mods *DO* make a difference. Sure higher compression is nice, but the above mentioned mods will still increase performance.440sixpack wrote:I'm not attacking anyone. I'm just not back slapping and shining him on. it sounds like he made up his mind up before he asked so why ask for " opinions " if a high five is all that's desired. it seems there needs to be a tech forum and a support group forum.
There was never any reason to waste the money on a 4V in the first place because it would do no good on a smogger . so the intake would obviously be useless. headers on a street driven smogger are useless. changing the cam in a worn smogger isn't going to hurt anything but gains will be minimal . and without a new valve spring set even more minimal. so what did I get wrong ?
The OP asked for opinions and he got something he didn't want to hear. the truth. do what you're going to do it's not my problem.
