Smaller pulley than stock 289 think it is from Fairline, Alicool aluminium rad, flexi fan plus 14" pusher fan. Car runs at 90 on gauge never moves. Do not fill in side vents, works in slow traffic but needs the extra air when moving fast. Check out my engine bay on eBay Uk Alicool rad. Hope my five penny worth helps. Bill Sincerely Bill Tolson
