What size is that head (I obviously don't own a socket large enough) ? I know it's bigger than 1 1/16 !

Here's the dealio - we got my newly built 340 running good BUT - simply bolted the 770 Avenger on out of the box and set timing to what "worked". Obviously (500 mile break-in done) it's time to get it dialed in right. Is paying for the dyno time worth it, or are the differences with a weekend...

Well, I see the "10 second small block" thread. It seems to me, as far as streetable, this is more "doe-able" with cubes - any thoughts on a 11 sec 440 build that'd be definitely street friendly ?

I want to make sure my heater and radiator hoses remain leak-free without over-tightening. My issue right now is the chrome filler neck on my manifold leaking - got the clamp super tight and it still wont seal (not at the base, around the hose itself). Someone recommended sanding the chrome neck...

Okay lay out the gasket sequence here - obviously I can figure out the adapter-to-block gasket - but I guess I wasn't aware of the one (or two ?) used on the bolt (a nylon and a cork ?) No instructions in my Haynes or "How to Rebuild SB Mopars" seems odd.

I have an aluminum timing chain cover .... I'm pretty sure I stripped some of the threads (why I say "some" is 'cause as soon as I felt the slip, I backed out (ARP chrome bolt, 1" , seemed somewhat short). Any way, I grabbed another bolt a half inch longer and it tightened fine. Was curious how...

Are these just for looks on street cars ? I was considering running from fuel pump to carb - looks great but no real advantages, correct ? I'm assuming they come into play when you want fail-safe parts on a race car ?

I have either to put in my Duster. If both are built about the same with regards to bolt-ons and pistons/compression - is there a significant difference in gas mileage (thinking about if/when gas goes back up).

Couple questions regarding lube. My 340 has a home-made deep sump oil pan, looks nice, they basically "mini-tubbed" it ! It measures 9" deep from flange to bottom of sump - what's the approximate capacity. Question 2 - 727 (stock pan) -what's the capacity with new convertor and do I need to fill...

Airgap has a stripped out hole for temp sensor - don't need this hole anyway, don't have ability to tap and plug - would JB Weld not do the trick or another recommendation ?

Asked earlier but didn't title it to get response - 1971 Swinger -1968 340 - .030 over - 727 - ported X's - fly cut flat-top pistons - maybe 9.5:1 - 268 cam - headers - Air Gap, etc.,etc. Was considering Autolite AP65's or Champ N12Y's - should I go a little hotter since comp isn't that high ?

Recommended spark plug for my car ( Lunati 268 cam - 770 avenger - TTI's - 727 w/3500 stall ) Thanks. also have two kickdown assemblies to choose from - make a difference ? Edited content ignore title !

First time I've installed an aftermarket - the gasket in the Fram rebuild kit pretty much shows all the way around (larger than Air Gap intake) Do I need an aftermarket gasket or can I mark and cut this one down - or do I paint it the block color and move on ?

Do you use an oil pump gasket or not ?

Do most of you check gap on rings out of the box (Speed Pro's) or install and go ?

I don't want to stop for the day - crank end play seems to be about .0015 - do I have to get the thrust bearings shaved or can this ride ?

Lost my old camshaft keyway - new Lunati cam doesn't come with a new one, can't find one on-line - would NAPA or Advance have these ?

1968 340 - the Fel-Pro kit has a rear main seal that has block half as half circle and cap half is half circle with "ears". Book shows both halves as half circles and ears ar separate, allowing for the "offset" placement of the seal (which is a better seal - so they say) Two questions - is this...

First time at reassembing my own engine - All has been checked for clearances, etc. Read through "How To Rebuild Small Block Mopars", watched an instructional DVD, doesn't look too tough so I'm gonna proceed tonight. Any advice/tips or common mistakes to look out for .... I'm sure there's a...

Looking at a Duster, advertised to have a 366", 450 hp motor. What's the makeup of 366 cubes, don't believe I've come across this build before ?

The only machine shop in my vicinity aren't the most talkative bunch. I need some insight before we button this thing up. Any thoughts or concerns would be appreciated : Bottom end: 68 340 .030 over TRW L-2316 forged flat top w/ 8cc valve relief, .030 above deck (shouldn't be an issue from what...
