Sure but how long will they last - they will eventually get bore walk and HG failure at that level IMHO
450 lasted 10 years/ 18k miles for me with an obd before it went as above
At least it gave you plenty of time to save up.
I would imagine a great deal depends on how it's going to be used, in a road car there aren't too many places you'd be kicking the **** out of it for prolonged periods, it would just be the odd squirt here and there for 5 / 10 mins at a time max unless on a track day or at the ring, but anyone who takes a standard engine close to 500bhp and then regularly kicks the **** out of it on track is most definitely on borrowed time and the same can also be said of a built engine. I'd say most would be happy to get circa 20k under those circumstances.

If taken care of properly and not driven like a boyracer it should last all the same,but that's the rub right there,to get the best out of modified engines meticulous servicing and maintenance plus a little mechanical sympathy has to be applied,like anything you use continuously hard,if not treated right be prepared for the engine to grenade itself.SJ.
Up pipe is on the list and ported headers, will contact as performance for these. Going to try sticking with the top mount
Andy Forrest ran/runs a TMIC on one of his track orientated scoobs, can't remember the power levels, certainly 400-450 I expect. He said it was a good set up but needed a cooling down lap every 2-3 laps or something along those lines.
