Single or Dual Plug

Is that a single plug setup? The heads appear to have one spark plug.

Thanks for sharing.. cool looking!

yes

May I ask why you chose to go with a single plug setup in a 3.5L motor?
Thanks Mark

Twin plugging is a luxury that should be considered way down the list as far as performance options are concerned.
Bang for the buck is almost silly. This a street cabriolet for heaven sake.

Very clean....nice work.....

going 3.5, was there any concerns around using the SSI's as distinct from a larger exhaust choice? I thought the SSI's were considered as a little to restrictive for a motor that size ?

The choice of exhaust was more about availability of quality heater boxes and economics than choosing the optimum exhaust tubing size.
In a perfect world a slightly larger primary might be desirable for higher end operation but for the purpose of this exercise, the SSI seems like the best compromise.

Nice! All that gold plating makes it look like P-Diddy's engine! :D

I try not to play the horse power prediction game but I would guess 265/300.
But the truth is, unless you're willing to change parts "you get what you've got".

265- 300 Wow !. Regardless of what the final number is it will be strong motor and a great ride.

I have to admit though that I get confused with how successful these 3.4 and 3.5 upgrades are in increasing power from a 3.2. If a 3.6 with higher compression puts out 250 HP, i am always baffled that a base 3.2 upgraded to a 3.4 or 3.5 can exceed what a 3.6 puts out so easily?

Better exhaust and better cams are the key as well as the higher RPMs achieved by these smaller engines.
BTW: that's 265 hp 300 ft/lb of torque
