Nice....how's it doing? Any numbers?

Badass

Still waiting....

Coming along nicely

Normal..... Dont worry....

Wow,...I knew him., and didnt know he passed....my sympathies. AND I'm 13 years late.....( 2007 !!)

The correct spark plug for SBM Forced Induction is : NGK 5671-9 But you might be able to get away with a NGK BR8ES

I hear you. 2020 wasnt good to Anyone. Hoping the best for you. I have a new project car, and a pile of parts in my Closet. Looking forward to 2021. Happy New Year

Any progress updates?

Nope, ........Use a Ebay GT45

Hope you continue with this.... Lots of good stuff going on here.....

I've never had a 318 on a dyno. I have built a few. 318s have low output because of the 3 C's Compression Camshaft Carburetion #1 being Compression....all 318s were 9:1 or less. Custom 318 pistons are pricey. Someone really should dyno a 10-11:1 318 combo, but not many people buy custom...

Yes,... 8.50 cert since first built in 2003.

I have more, plus videos.... If interested PM me for more details

Ok...

Last time a seller told me that..... I got the car home drove it around a few weeks and noticed a "lifter rattle"...... I did everything everyone has recommended, changed the oil, inspected it... Sometimes it would do it, sometimes it wasnt as noticeable...but when warmed up it never went...

It would surprise everyone...... By my math.....(and I dont claim to be any kind of mathematician) 235 x 1= 235 x 2 = 470 at 14psi 235 x 4 = 940 at 28psi 180 x 1= 180 x 2= 360 at 14psi 180 x 4= 720 at 28psi Either 273 falls right into the range of a GT45 or s475. And a 273 can make More NA...

I want to see a 273 (any year, 9:1 or 10.5:1) Stock Bottom End....get a 70mm turbo installed....and turned 6500 with 7, 14, 21, 28psi.....and prove what exactly one can Take, and what breaks first.

Do a big bang 318..... Dyno test it 7, 14, 29psi....... Inspect what breaks...repeat.

The typical RN12YC Champion converts to a NGK BPR6ES......I was using a hotter NGK GR5. I expected to gain 200hp.....so 4 heat ranges colder (to be safe)...... I could have used BPR7ES, or BR8ES, but.... There is no BPR9ES.....at that point the correct plug is the 5671-9 copper.

Understanding Spark Plug Heat Range.

Let's not conversate on this thread.... But agree that for every 50hp above stock, 1 heat range colder spark plug is "recommended".....like nitrous/timing.

Well, I found the NGK GR5s to be the root cause of it....... I swapped the entire turbo setup onto a 318 and installed NGK 5671-9 plugs gapped at .028" in it and had no further issues, even up as high as 14psi on pump gas.

Hope your running a Cold Spark plug like a NGK 5671-9.... I popped a headgasket and piston on my 360 real quick because I forgot to swap in Colder plugs before the first test drive.

The time has come to let go of my father's 1969 Dart Swinger Drag Car...... He broke his hip last year, and had a heart attack this year....and he agrees it is time to let someone else take over. Here is the Specification List: 451 Stroker, 75 400 block, forged crank, forged rods, venolia...

I've ran a Edelbrock Performer with a thermoquad, a RPM Air Gap with a Edelbrock 1406, and a Weiand 7515 x-celerator single plane, with a Holley Double Pumper. I swear I felt a 50hp seat of the pants difference with the Weiand and Holley.
