Odd but radial drag racers now fit a 275x60 Radial Pro over a 12"-13" rim in outlaw and x275. 235 Radials are been strung over 9-10" and running deep in the 8s.

I run a cooler around mine???

Copper is worth alot more than ally. Mine is a stock AC falcon sedan rad I paid $50 for.

Stock copper radiator works just fine. Mine uses a AC copper radiator and I haven't had to turn the fans on unless im trying to cool it after shut down. Even when pro charged with a single 14" fan it never got hot?

Modern NA 4 cyl cars have twin 2" - 2.25" exhausts. You have to get it out of there.

And a 2.5" is not big enough. The old twin 2.5" on mine was stupid added weight but worked well,however a single 3.5" would of done the same with half the weight. If a exhaust sounds like poo it's cos there's not enough engine in front of it.

Stay out of this you...LOL

They sound no different. Only way to make a exhaust sound good is to put a stout engine on it.

6-2-1... So 2 pairs of 3 into 1 merge into a pair of 2.5" collectors into a single 3.5" merge collector then back into twin 2.5" pipes. Single 2.5" is not big enough tbh.

My 850hp rated C4 uses BW clutches x5 and the bands from memory.

Its got a 84 DA seal in it but needs a 86DA unit. Same size as a EF seal.

You need r's on a EFI engine so you don't cause signal interference

Sooooooo...tighter you set em longer they last usually but there is a limit to both sides of that comment. Some work on x.007 of bore. I actually set my Wiseco's at 15th top and 2nd 17th 8 years ago. After much of that time NA and 8200rpm and later a P1SC Procharger I pulled the bottom end down to ready for a freshen up and found there at 26 and 28th respectively. My turbo combo will be set up the same with 26th top 28th 2nd. So I never go crazy on ring gap and TBH 20-22th and 22-24th on a stockish engine set with 3or 4th piston bore clearance is heaps IMO.

Pushrods and lifters (if flat tappet) do too. Along with valve springs if you watch a spintron in action.

So first thing to know is the rings rotate in the bores as they go up and and down so don't stress too much. But for the argument I set the oil rings 180 apart from each other and find a spot on the piston im happy with. Then the 2nd ring goe's as far away as you can get it from the "top oil ring" gap. Then the top ring is 180 opposite the 2nd ring gap. But the rings still rotate in the bores at there own rate anyway so don't be too concerned.
