Target was 300bhp, Done alot to get there:
High ratio roller rockers (Titan motorsport red)
Stage 3 heads - tripple ground seats (10 bolt)
comp ratio 10:1 decked block
ported inlet manifold
TVR 4.3 crank fully ballanced
V8 developments stealth cam
double valve springs
vernier pulley
...But Due to block hugging manifolds been quite poor... I recon around 280 (ish)
Goes like a riot..... Especially with drum brakes and leaf springs!!!!!
