    CNC Ported Heads for 318 Poly?

    There is/was a fella on the B body site that went to town on porting the poly head on his build. Sorry I can’t remember his name. He was doing unusual stuff for his build. Custom domed pistons etc… I hang out with Charlie Servedio in which you can copy and paste into the YouTube search bar to...

    Carb recommendations for my 340

    That’s true. I have an 800 AVS on my 10.5-1 - 340 with a XE285HL. Actual flow, IDK. I did flow test a Edelbrock 600 AFB and it did flow 600 cfm. I was toying with the carb grinding away at it and managed a best of 715 cfm - IIRC. I did this on Charlie’s flow bench along with a video on it. I’ll...

    Carb recommendations for my 340

    He probably didn’t proofread the mistake. I’m pretty guilty that myself. I’m pretty sure this member knows that but 650 AVS is what I think he was after.

    Is the spool mount k-member worth modifying/reinforcing and what should I change on the suspension brakes?

    Reinforcement plates welded to the bottom of the lower control on? That could be done. As to the key frame itself, I’m not really sure. I’ve never had an issue with them. Perhaps check with Mancini for bushings to see what’s out there. I’m sure they’re asking top dollar, but, at least you know...

    I wonder if that carb is “Legal” for the OP? How many cfm’s George?

    Well I won’t go as far as Lord but he is correct. He gets a lot of crap from the board and sometimes I have to agree. I’m like - “WTF did he just say !?!” But in this case, I agree. When you break it down, an engine (over simplified) is just an air pump.

    year one, problems, anyone know this?

    I can’t stand that crap, total BS! I agree! They should have the decency to be upfront.

    At toolman - The rant is in fun… but honest And what was my reply to that and the subsequent reply to when someone mentioned about the crack in the head? So now we’re on Rinse & Repeat? I like that idea. I did the same-ish, when my daughter wrecked her ‘00 Durango. Nabbed that 5.9 right fast.

    Cheap 318 performance mods.

    I’ll just say, your of no help. Re read the original question and answer it, or not. Spending more money on another engine isn’t the answer to the OP’s question even though (from a certain prospective) it makes sense. And I’m not arguing that point ether. But then again, that’s not answering...

    Cheap 318 performance mods.

    I won’t argue that but then again, I think a re reading of the original post is in order to better answer the actual question asked by the OP. If the question was not, “What can I do cheaply to my current 318”, I’d say your answer is perfect but it’s not along with a bunch of others here making...

    Define? It was defined. It was in the 1st post by the OP but yet again, the thread devolves into the ridiculous mantra of spend more money! He asked for cheap effective 318 engine mods only. Nothing about a converter nothing about gears, just the engine. The first mention of 360 - 408 ,AKA...

    Cheap 318 performance mods.

    Even though I recommended against there use, this is what I am doing right now. The cracks appear in between the valves and effect nothing unless there huge. The cracked heads are currently up top a 5.9 in a Duster with an old Crane Hyd cam, pictured below with the normal bolt on HP parts. The...

    Between abodyjoe & AJ’s recommendations, those two (distributor recurve and torque converter) will give the best immediate bang for the buck with the most noticeable results.

    360 head over a 318 because flow trumps compression every time and has been proven over and over again and again. To that end, ai’d walk right to an aluminum head over a cast iron 360 head.

    Cheap 318 performance mods.

    Skip used Magnum heads. IMO, skip them in full unless they are the MoPar R/T Magnum heads, (LMAO - Good luck finding these hens teeth.) or use Edelbrock Magnum heads. A readily available and very good choice.

    Cheap 318 performance mods.

    Welcome aboard! 318 Willrun covered it well. I’ve done a few 318’s over the decades. My advice? Don’t bother with the 302 heads, use what you have. The 302’s aren’t that good as cast but can be ported out really well. In my opinion, skip porting them UNLESS you can port them yourself...

    I Chose the 383 Big Block

    If you had read my reply, I don’t think you’d be writing what you did. As to directly reply to your post, I agree. For clarification purposes only. I have had a low deck B-400 in a ‘71 Duster w/a 727 & 4.88 gears. The car was gutted and a pair of basic race buckets installed. SS springs, 6...
