My project is a mm based H-Mod race car that was raced in the late 50's and early 60s. I need tech specs on how to install the Alta head and would also like to update the front and rear suspension to Sprite /1000 parts.
Sprite front suspension is totally different to a Minor. You can use the disc brakes though, but they are very small so hardly worthwhile - better arrangements are available. The rear axle is a lot narrower than a minor, so same applies - best upgrade is to a Ford escort or similar, but I'd suggest a standard Minor 1000 axle will cope with the power you will have. I can't help with the head, but there is plenty advice on other minor forums:
