Default bought a SR intake how long to install cam!

Well I bought a super ram and now I am thinking since it will be apart, and they say with out heads and cam it is pointless I am thinking of finding a lpe 219 cam and some good matching heads . I can do most anything on the car but I can't set up gears, and I am afraid of the cam install. I saked the shop that will do my pumpkin how long for a cam and they said 13 hours atleast! can someone tell me how this is! I think racers and wrenchers can do it faster! and I figure if it has to come apart why not bolt all new stuff on right away!

90 auto will have 3.75 gears, around the town car so no crazy rpms at the strip. the sr will be ported. I like torque and mid range.

what is a good cam
what is a matching head set up

thanks

I think 13 hrs sounds about right for a Heads\Cam install.

Heads cam, and intake will require every minute of a weekend, and more. If it is not a daily driver, I would do it over 2 weekends.
Be careful if installing a roller timing chain. They always hit the block, just above the middle oil galley plug. Therefore, alot of grinding is normaly needed to clearance it.

13 hours is pretty much "book" time.

You cannot go wrong with the 219 cam from LPE it will work well with the superram. Any good alum head from AFR, DART, Trick Flow, and others will work well, what you need is a small combustion chamber, and thin .015 steel ship head gasket to get the CR up to 10.5 to one. The higher compression ratio will optimize the combination and make good power. The heads will probably need to be milled to acheive a 57cc combustion chamber volume to work with your stock L-98 bottom end. Make sure the people who install the cam degree it per the cam card.

If you plan on doing this in the car 13 hours is going to be pretty close. I have done a few of these in my shop and with lifts and all the right tools it takes me about two days to complete the job. I find it much easier to just remove the engine, especially if you have an automatic transmission. I just pull the engine out, get the engine on a stand and go to work on it. Doing a cam job is a PITA in a C4 when the engine is in the car. I can just about have the engine out of the car before someone can remove the radiator, AC condenser and the front balancer. The LPE 219 cam is proven combination, there maybe better cams out there today such as one of the new Comp Cams XFI series for the SBC.

I have used Trick Flow when they came out with their twisted wedge heads. A couple weeks after I got it installed, they said their guideplates had some defects in it. I had to have their new ones installed. OK. A couple years later, I found a broken spring. (I did buy their HD spring kit). Decided to take the head off and found that the valve had hit the piston and broken it and scored the bore. R&R time. Had the heads checked and found that the side with the broken spring had loose valves. All of them wobbled in the head. The other side was fine.

I had the heads repaired and sold. Bought AFR 190s instead. Should have gone bigger then but oh well. Anyways, I wouldn't trust anything from Trick Flow on my car. If I had to use their heads, I would get a bare head and put my own stuff on it.

The early twisted wedge heads had problems, the 195cc conventional heads have been very good. I have had no issues with my 195cc heads.

Maybe so but I feel the problem was with their QC using lousy parts. Would I chance another motor? Probably not. Hence I recommend against them. Maybe they have improved their QC. I don't know.

If I have they pull the enging there is absoloutely no way that a 350 is going back in!! I guess if it is easier to do a swap for the price of things lately I could just buy a 383 or something biiger rather than invest in parts and labor on an old 350!
