Starting to look at engine options and have been considering a 408C stroker for a while now to wake up my slug Aussie 302C
There are some kits available however there is a sale on at one of our major performance warehouses and they have a crank and rods on special I can't resist but not 100% they will do the job without requiring custom or special pistons, balancer, timing set etc.
As an example 408 forged kit dished pistons $3300 AUD - crank/rods $1385 which leaves nearly $2K for pistons, rings & bearings
The crank is a Scat 4340 standard weight forged 2.750 main journal 2.100 big end journal however the required rod length is 6.125 which is unusual. Scat part number is 4-351C-4000-6125 or 4351C48 which is no longer in their current catalogue. I found it in an old 2009 catalogue online and they are listed for 351W with 351C mains (use narrow bearings?)
From what little info I can find many of the Scat stroker cranks are a hybrid of some sort and can be used between 351W & 351C providing you use the correct balancer and timing chain set which shouldn't be too hard to find.
The con rods on sale are Scat part no 6612521QLSA which are ultra lite h-beam stroker rods (Chev type) which will suit the crank but my main worry is getting the right piston being as this crank must have been phased out.
Anyways would appreciate if anyone has experience with these different set ups. I might even email Scat themselves to see what they can tell me but the sale ends soon so I need an answer soon.
