Hi all, this is my first post - I searched, but hoping for a little advice specific to my setup.
For the last 5 years I have been the very happy owner of an Aus Morris MK1 850 with a Minimania built 1380 supercharged engine, amongst various other performance mods. The engine currently has / is:
- Autorotor pull through supercharger, 7psi
- 8.5:1 CR (from Minimania info on engine build)
- HIF44 carb
- 731 cam
- Alloy head (C-AHT345)
Dual valve springs
A+ sintered rockers
LCB 1.75" manifold, jet hot coated
2" single box exhaust
Aldon yellow, Pertronix Ignitor II & Flamethrower II
Other than starting difficulties in cold, the thing hauls and I love it. Curious about improving performance, with best bang for buck and without chasing my tail on diminishing returns. Happy for advice or any other feedback outside of what I might be looking at.
Question, are 1.5 roller rockers worth it on this setup? And any recommendation on Minispares, Minisport or MED? Would anything else be require after installation, just a retune?
