I agree with everyone above also your 318 will need a different oil pan and a v8 steering center link. A nice healthy 225 would be a better "Budget option". By the way is that a Canadian Valiant? I can't tell by the side shot with your helper.
Thank You for responding, No, this isn't a Canadian Valiant...my son really enjoys the car and I was hoping to have this fixed before summer so that we could enjoy it...maybe asking too much.
