    Thanks for the info guys ,I assumed in my ignorance that the lower profile manifolds were about the same. I'm thinking that the holley would be best for me as I'm used to them and injection might give me problems I can't fix myself. Looks like a 390 on top of a dual plane manifold for the lower RPM range would do me for now and if it can do 25 MPG that will be a bonus

    i used the webber carb set up on my last rv8, brand new 4 barrel, with edelbrock manifold was superb, fired straight up out the box, minimal tweaking to get the mixture spot on and never faultered

    injection as said above is simple to set up and looks good i reck, for an everyday user probably the cheapest and best way to go

    If you want an injecton set up a mate has a complete one for sale for 70 ,no idea what it came from but could get pictures if it matters.

    injection, its easy to wire only 4 wires once the loom has been seperated, better performance on a stock engine, the only extra thing you would need is a return line to the tank,

    Should make it clear that Kev is saying stay clear of the offy 360 as the jwr duel plane was still an offy but much better,

    The Offy is a 3000 rpm upwards manifold, low end flow is poor, the other 2 feature split inlet runners meaning better air fuel velocity / atomisation .This leads tobetter bottom end pick up and economy.

    The Offy gained popularity because it was once the only manifold you could buy and are fairly readily available secondhand. The other 2 will pay for themselves with the performance gain and better fuel return.

    just curious kev why not the offy in your opinion
