I suspect this will have been raised many times so feel free to direct me towards the relevant threads!
I currently have 302 with original heads and cam. It is fed by a Holley 600cfm Quad Barrel carb and makes 280bhp on the rolling road. I am trying to decide which way to go with heads and cams. I am aiming for a 'balance' of around 80% fast road, 20% tack day capability.
My initial thought is to use a matched set of Edelbrock RPM Performer heads, intake and cam. If you have a similar set-up what sort of power is it actually making and how is the drivability?
However, whilst looking at the AFR web site I came across a article form 2003 where a stock 302 had been fitted with AFR heads and had retained the original cam which was 'hotted up' with 1.7 ratio roller rockers. The article claimed 400bhp (I assume dyno rather than rolling road).
Has anyone actually gone down the route of using good heads and 1.7 rockers (rather than a new cam) - and what was the actual outcome?
All the best
