At this point, I'm just doing some gasket matching, pushrod relief, valve boss blending. My question is, do I dare touch the short turn/bulge further past the pushrod tubes? I plan to do some bowl/seat work on the exhaust bowls, but the intake bowls look plenty good ootb. Any advise is...

My front clutch is on borrowed time as it flares in 3rd. So to bandaid it I decided to throw in a transgo SK I had laying around. Upon removing the low/reverse piston, I discovered the cushion spring was broke. Any Idea what could cause this, or is it just common from fatigue. What might be some...

I understand the higher the ratio, the tighter the band clamps the drum and quicker it shifts. But, why so many different ratios? Is a 5.0 too much for the street? How hard would it shift? Any other input is much welcomed. Thanks

Hey guys, I just installed an E Curve dizzy. Those who don't know, its a digital diz with its own built in ign module. It allows the user a variety of custom tailored advance curves that you set by following a graph with corresponding letters and numbers that you then set with little dials under...

My 86 ram with a freshly rebuilt 408 refuses to start. Its been on ongoing issue with both the mopar ignition and now with the msd 6al. The old teener it replaced ran fine, well, never a no start issue that is. I have 170 in every hole, got fresh gas (ether too), good strong spark, but no...

I got a 6al box that's hooked straight to the bat, and orange wire on the + coil and black on -. The purple and black to dizzy and the little red (rem/trig wire) to the constant on the ballast (ballast is bypassed). All connections are clean and solid, I soldered and shrink warped them all...

I finally got my 408 running and broke in however, I seem to have some valvtrain noise. Its not bad, but its audible, sounds a little louder than a sewing machine. Its got a comp cam (I don't recall the part#) its pretty mild 224 @.050. Then its got hy-lift Johnson liters and smith bro push...

Hey guys, I finally got my 408 in my 86 W150 but heres my problem. Right now it'll run on the "start" position but immediately dies in the "run" position. Its been converted from lean-burn to std mopar electonic ign with an orange module, 2 terminal ballast, 2wire dizzy.*...

I'm looking to run dual (rear) breathers on my cast MP valve covers, only problem, is they notched both holes for twist on cap/breathers. Anyone know of a twist on breathers that looks like this http://www.summitracing.com/parts/KNN-62-1160/ and/or a grommet big enough to cover the notches so I...

I have a gasket matched eddie RPM performer intake (from hughes) and unmatched RHS heads (from IMM). Surprisingly the intake runners on the head match up pretty well other than a couple corners and the typical pushrod pinch................................... Your probably asking why I wasted the...

Getting ready to start assembly on the 408 in my sig, anyone care to share some tips and do's/ don'ts? For example, I was told to only file one side of the ring as to keep the gap straight. Also, when cheeking the main clearances, its possible to torque 1,2,3 and not disturb the plastigauge...

I've done some searching, but not sure what my best option is. A) Run stock bolts B) Run 12pt bolt w/o washer and slightly clearance pump C) Grind down stud and use a 12pt nut w/o washer and clearance pump D) Spot face cap enough to use the std stud and 6pt nut w/ washer, and no pump...

My 318 has been running like a dog (more than norm) the last couple weeks, so I decided to pull the plugs and have a look see. To my surprise I find that the entire passenger side bank has ash deposit on the grnd straps (typical for the #6 cyl). 1,3,5,7 look perfect. I realize ash is usually the...

I'm getting ready to paint/assemble my 408 and need some ideas on color accent/brands/prep. I'll be using black wrinkle mopar VC's and A/C lid w/ an aluminum intake. I'm wondering what else I should paint and not paint. My oil pan is a brand new stock replacment (spectra) thats already black...

Coming down home stretch w/ my build... I know, I aint been on in a while :oops:. Been working like a mad man. You guys probably forgot me by now. I'm the kid building the 408 for my 86 4x4 w/ O/D as a DD/weekend tower/wheeler. It'll be mostly city. I need help deciding on what ring...

I'm cumming down home stretch with my build here and need some bearings for cam,rods,mains. This (as many already know) will be for my 86 full size that will be a city driver/weekend hauler/wheeler. Pretty low rpm application. Scat cast crank and I beam rods. What are my options? What do you...

I received my crank yesterday. I'm a lil surprised to how much material they removed on the throws. Heres some pics of 7/8 but 1/2 look identical. The last pic is what the unmolested 3/4 5/6 look like. Is this normal? The 3rd pic is at a poor angle...

I got my Scat crank today. When I unboxed it, I was surprised to find that there was no support in the middle to prevent sag. Just some styrifoam end supports encased around a cardboard box. I was always told to NEVER lay a crank on its side. Is this just a myth? Sorry for such a big pick

What would you guys suggest, I'm building a daily driven 408 that will live in the unforgiving climate of ND were temp can range from -40 - 120 deg. Not the best environment for hp motors, lots of sacrifice and compromise. One of which is piston alloy. I'd like to go forged but the req cyl...

I'm building a 408 stroker using 68cc RHS heads and .030 KB/Icon pistons. I need to keep it pump crap happy(91). Looking at the 27cc IC983's (9.1:1), there designed for the mag blocks with a 9.585 deck height vs the 9.599 LA. Which means I'd have to shave .030 to achieve zero deck for a desired...

Anyone using or familiar with these? I guess they have a lowered oil band to help with oil control in LA blocks. Any idea what the "general" MAX lift is with these and others b4 you need a custom ground cam w/ a smaller base circle? I dont plan on lift higher than .525. Any idea as to how...

Well, I need to replace the oil pan on my 82 4x4 360la. Can I use a stock 5.9 mag pan and one piece gasket as a replacement? Is there a better option than the felpro (FEL-OS34409R)? Does the felpro have a steal core to prevent from pushing out? If so should I put a light film of permatex on...

I'm new to the whole roller cam so bare with me and my ignorance lol. The cam will be 228 538-548 on a 112 or 113 lsa. I guess my question is, who makes the best lifters that will literally drop right in and suit my application? I've been looking at comp/crane/lunati/herbert/hughes, but is...

I know I don't belong here lol, but it seems alot of knowledgeable sb stroker guys hang out here. I'll have a dart/duster/scamp some day, although I'd rather have a challenger/cuda/roadrunner. I love all mopars and were all the same family at heart so don't flame me for being on FABO with a 4x4...

Hey guys, glad to be a member of FABO even though I dont have an A body since I cant afford one lol. I got my mopar passed down to me, I'm the 4th owner of an 86 W150 318. My grand pops was the 2nd owner and my dad was the 3rd. So the truck is a third gen mopar and I'll do everything in my power...
