Everything you guys are saying is valid, I'm not disputing that at all. I just got this car so I can have "hands on" work experience with cars and such. Both of my other cars are "newer", in the idea that they have a lot of computer controlled parts/ecus, and the amount you can work on them internally and so forth is fairly limited without a deeper knowledge of the car. I just had my heart set on a new cam shaft as that was the direction I was guided towards.
Swing, for a pure stock car keeping everything as it is here are your best choices and why: Erson cams:The cams are made to make the best of the small valves and combustion chamber design. RV10H; smooth idle broad power range better than stock from idle to 5000 RPM; will work best with carb update to two barrel Weber/Holley RV15H; Good idle (slight lope);Lots of torque with a broad power range. Needs the carb update and headers will help. TQ30H; mid range power with lopey idle; needs tri-power and headers with dual exhaust. All cams are hydraulic cams and I recommend that you get the kit when you order the cam. It has hydraulic tappets, dampened springs, chrome moly steel retainers, locks, valve spring shims and a tube of Moly lube. All kits are for stock heads with no machine work. I would think that the RV15H (#280201) and 1H (#828010) kit would be just what you are looking for. You will get a substantial boost in performance (especially with the addition of headers) and the idle will be reassuring to you.
" just had my heart set on a new cam shaft as that was the direction I was guided towards." so why is it so hard to be guided in another direction? if you just want to do something to your car you don't have to ask anyone. just do it. let us know how it turns out...if you need any help just ask... the 250 is a simple motor to work on..(nonadjustable rockers) i have the tool to pul the lifters if you would like to borrow it. i got it at Advance auto parts for about $15 bucks.(maybe less) ......
that RV15H or 10H sounds like a pretty good piece for my 250. any ideas where i could look to get one? does summit sell thm?
i couldnt find them listed on jegs or summit and i went right to their website and couldnt find any cams listed for ford I6's
lol I never once asked permission to do a camshaft and I never said I wasn't going to. I just, from the get go, wanted to know which would be a best selection from the dozen camshafts offered. But thanks for the suggestions, I do appreciate them.
I've heard a lot of good stuff on RV cams. So is Inlinesix.com the only place that offers 2 barrel carb adapters? Don't crucify me, I'm still pretty new to this stuff and what sites/distributors you guys are used to using, and they are the only ones I've seen.
go in the tech article section and look for my post about putting a 2bbl on your I6. the adapter plate im using is only like $14 from summit
Inlinesix.com is a message board, like this one but they only discuss the inline 6's. They don't sell parts but they can tell you where to get what they have used. There other ways to mount different 2bbl carbs - the Ford 2 bbl is one that I have mounted to a six and it worked very well. You have to machine a flat space big enough to mount an adapter to and it is opened up so the bores have no restriction into the cast in manifold. The adapter is bolted on so the throttle lever lines up on the manifold side of the engine. The old throttle linkage works well with the Ford 2 bbl. You have down-shift linkage for the C4 and it is a simple way to open the intake side to better breathing. I switched over to a 170 rocker assembly so I could use a mechanical cam but with a hydraulic cam you won't need to do that. I built a C4 and a distributor for a guy who ran an alcohol rail based on a 200" and he had the manifold milled off the head and mounted side-draft Weber carbs to each intake port. For those of you who think all sixes are slow should have seen that rig go down the quarter mile.
