More BHP

[Mr WST]

Your advice please!
Looking to get some more BHP out of the 420SE, probs looking at a CAM upgrade. Any ideas on the best cam for more power, any one changed a cam and where to buy?

Thanks

New cam & followers would make a difference. You can basically choose where you want the power. Low down or high up. Mine has got a high lift cam & it makes great power from 4k rpm to 6500rpm. Where as my old one had a stump puller cam & used to go like stink from 2k rpm to 5k rpm. Different 'feel' altogether. You should be able to chose what you want with a carb as adjustment won't cost too much.

Thanks for that
2k is where i want to be sat back in my seat. Not really bothered about top speed, just how quick i can get there!
Anyone know of a specific cam...?

Talk to Ray and Shaun at V8 developments in Lincolnshire,they sorted mine for me.

The stump puller is a specific type of cam

[Mr WST]

Thanks for that, will have a chat with them guys and look at that cam

[Mr WST]

I'm running with a 600cfm holley carb at this time, if that makes sense.

I'm running an RP1 cam from RPI Engineering in my 390, torque curve looks like this:



240 lb.ft from 1600 to 5500rpm. Peaks about 280 lb.ft at 4200rpm. No real shove in the back but goes quite well
