89 Lx . Going to used for autocross. Its been awhile since I played with pushrod engine. I was wondering if you guys have experience or thoughts on a particular camshaft for application. Stock bottom end aluminum heads 2.02 and 1.60 valves. 64 cc closed chamber. 5spd. 3.73 ring and pinion. Its been over 25 years since I put one together and a much larger selection of camshafts available. Large valves and chamber to allow for supercharger in future. Thoughts and Opinions please.
