I looked at other Treads but---------------

Here is what I have: (new rebuilt long block)
4.040 bore
3.48 stroke
GM 3970010 4 bolt main block
Sealed Power H345DCP hypereutectic pistons
Hastings 139 rings
MS 909P main bearing set
CB 663P rod bearing set
Durabond CH8 cam bearings
Engine Pro 3001 timing set
Engine Pro camshaft 214*/214* .450/.450" valve lift @.050" lift
Johnson HA817 lifters
Fel Pro 260-1000 gasket set
Melling MPE 100 freeze plug kit
Melling M55 oil pump

Putting on Edlebrock/Quadrajet/HEI along with Ramhorn exhaust to 2 1/2" dual pipes.

Spark plug recommendations ????? Champion 113 at .045 is what I have so far after looking at all threads etc. But I am sure I am overlooking other possibilities.

Dude, Champion? Autolite? Are you a Ford guy trolling the Chevy forums?

LMFAO You young guys are a riot. Its a spark plug not a life and death decision based on brand. Just looking for what works. To funny. At 71 have more to worry about than brand names. FYI bought Autolite AP145 Platinum for $1.60 each after all Rebates delivered to my house.

In that set up the name brands will not much matter.

We use Autolites in a 700HP dirt late model engine and it is a SBC to boot.

To some I guess there is a line in the sand. LOL
