    Nice! Don't forget to order an airbox for that and if you can swing it, a jet kit

    Here's a great source on how to go about jetting almost any Weber (scroll 1/3rd down the page to find "The 3 Circuits" section and go from there)

    Nice, let me know how the car runs with it. I realy wanted to put ether bike carbs or a 38 on my EXP but chose to stick with EFI since I had all the parts.

    would the EFI make more power then a well tuned weber 38/38?

    I need more RPM in this 1.9 best cam and valves you have a idea?

    From what I have read the stock carb on a 1.9 HO dose a tick better then the EFI form a performance stand point.
    So Im betting the 38 would be way better. But I cannot be sure as I never used a 38 before.

    EFI will be better than a 2-barrel carb but that's mostly due to the intake manifold design more than whatever carb you use, unless you're clever with deflectors in the intake right under the carb the 2 outer cylinders will always be a little leaner than the middle 2 which make some difference in performance (like having multiple carbs out of sync with each other, this delays throttle response) and engine longevity if you're already a little lean to begin with you'll burn up your outer 2 valves.

    But dual Webers or bike carbs would be as good as or better than EFI obviously if you tune the carbs once fitted, it's just that the cost of high performance through carbs is a lot :/

    Follow the cam list I shared earlier in this thread, the roller EFI HO cam is the best of the best unless you can have one custom ground. Roller or solid lifters will allow you to reach 7,000rpm and beyond.

    You can try bigger valves and port the head, the pros in the UK found that increasing the intake valve size can make an easy 10hp before you do unshrouding or porting. But this depends on which head and cam you use..... When it comes to porting and valve sizes the rule with CVHs is not to enlarge the exhaust side unless you're turbocharging.

    But if you can port-match your manifolds and ports together that would certainly help. Polishing the exhaust port will go a long way too, it won't grant you much more power BUT it prevents carbon from accumulating which is a major flow-restrictor so you won't have more power but you'll have that power longer. Blending the seats is the biggest improvement for the time input, just blend the valve seats with the port's bowl/runner and you'll get about 18% more power across the whole rev range without having to change much if anything in your tuning (depending on how bad the seat blends were vs how carried away you get with the porting).


    Also try Harland Sharpe's roller rockers, the stock ones have a LOT of friction which translates to power-loss and valvetrain stress. Saw a video where someone put a set on a Jeep 4L in the dyno room and about 10hp was gained just by switching to Harland Sharp's rollers with the same rocker ratio. The graph was neat too, that 10hp difference was from idle all the way to redline!

    That is why I chose to not use a carb setup. Its all those little things that add up.
