I have built the 1380 engine to a high spec that can take the high revs needed to produce the power without going bang... (famous last words)
The 296 in my opinion seems to be fine in traffic, pulls very well past say 3000rpm, slightly lumpy idle which dosent bother me at all, the van is used as a 1/4 mile laugh/sunny day blast.
My question is going from a 296 to a 310 is there really a big noticeable difference in how they act and will I notice the difference in how they perform to each other? the 310 power comes in at around 4000rpm and runs out of puff at 8500+rpm. I know alot of it is to do with weight and CWP ratio, I'm running a 4.3:1 with a 3J LSD weight is around 750kg, 13" wheels (RWD) also has anyone used the swiftune sw23 or the sw310 using twin HS4's? Instead of a Weber or HS'6s with good results?
Thanks, Pete.
