XB Coupe Upgrades
Greetings to all, I am a newcomer to these forums. I have been reading them avidly for the past few months and the info I found on here helped a great deal in making my decision to buy an XB Coupe.
As I have mentioned on a post I found on a thread about the car I ended up actually buying (small world!), I am now the proud new owner of a 74 XB Fairmont Coupe in silver with orange GS Stripes. It apparently was a 'Continental Pack' with the vinyl roof but that has since been removed and painted although the chrome surround remains (see attached pic). Given the car has a GS dash and stripe, I thought I would get a GS grille and driving lights to replace the dodgy ones it has currently and a GS bonnet.I have also just bought an XB front spoiler.
The interior is in great condition, having been almost fully restored it seems to its brown glory, save for some staples in the driver's door (not sure why they are there!). It is now a t-bar auto instead of the factory column shift.
The car has its matching number 302 which is pretty well standard save for upgraded valve springs and cam (no idea what it is, Pracy may be able to find out??). It has an 8 inch borg diff.
The car currently has no power steering, but I have sourced original XB power steering and all the hoses, along with air con from an XF I think, both of which I am yet to install.
Seeking a bit more speed off the line (more torque rather than high revs).
From my reading, I am going to get some extractors, they seem to make a noticeable difference from what you guys have experienced.
My questions are : Should I paint the scoops on the new bonnet black? Should I use a separate switch for the driving lights (currently rigged to the high beam)? What colour should I paint the spoiler (if any, currently black).
The following may well be sacrilegious, so please let me know if this is the act of a moron and I should leave well alone! Should I upgrade the current 302 in the search for some more grunt and risk damaging the block or remove all the running gear and put it in the shed and put in a nine inch diff with 3.5 gears and rear disks to replace the current drums, convert to a manual toploader with single plate 11 inch clutch and put in a worked 351?? Would I be better off sticking with the C4 and the 302? I'm a bit worried about frying the diff and the C4 with a worked 351.
Lastly, has anyone had any experience with putting 351 2v heads on a 302 block? Is this worthwhile and what would the best way to do this? I ask this as I may have found a set of heads that have been already done?? I've read quite a bit about mating windsor blocks and cleveland heads to make a Boss, but couldn't find much about mating 302 cleveland blocks to 351 2v cleveland heads? Is this going to achieve much improvement in hp?
Sorry for asking so many I'm sure ignorant questions, but I'm very excited about the car! Cheers.
