Someone on this forum showed me this hillbilly clutch slipper that i intend on installing in my car. Maybe you will find it helpful as well.

Assemble the engine, install a small pin through the intake/head mating surface on each corner. dissassemble and use the gasket location to figure out where there is overlap and where there is not- when you're done you should NOT be as large as the gasket. intake to head alignment is all that matters, not the gasket.

I quick question before i order my cam today. Have you guys used Assault Cams? I found a really good deal on them and was wondering if its too good to be true?

I would pass on a Chinese cam since USA cams are not much more. Assault line is rebranded Pro Comp. look at Summit brand came if you want to save a buck.

This will surely make your car slower and increase the heat in the clutch and kill it faster. Best to just drop it. I move my foot sideways off the clutch not up. A slipping clutch can be killed in a day one that is dead locked will last its service life.

Drive line shock is best delt with in other ways.

There all made by the same company. 99% of all chevy and ford cams oem and aftermarket come from the same place.

Summit cams look cheap and use older grinds but really nothing wrong with them. But they are also not the best grind for long life. USally what you are paying for is not quality manufacturing but good design. Go with a good design price is mute once its whiped and the entire engine needs to come apart to clean and replace.

Here is a link about cams. FYI the companies mentioned are owned by the same people.

Sorry to bring this thread back from the dead but i figured it would be better than starting a new one. My greed / eternal quest for more power is kicking in and Im now thinking running the 1.6 rockers is a good idea as suggested by F-BIRD.

I have already ordered the cam from summit: Mechanical Flat Tappet 275/281,.505/.520
Howards Cams Mechanical Flat Tappet Camshaft and Lifter Kits CL110102-06 - SummitRacing.com

So I will have the following lifts:
Intake (.505" x 1.0666) - .022 = .517
Exhaust (.520" x 1.0666) - .022 = .533

How much power gain can i expect with this change?


Also below is a picture of my short block ready to go back together. The cam i ordered is on backorder and will probably get here in the 2 week of april.

You will most likely find the most gain by just using the 1.6's on the intakes only.
The exhaust side responds more to duration changes than lift changes.
The changes will be small at best.

You can play with the lash too. start at a cold setting .004" less than the hot lash spec.
If/when trying a bigger lash setting do not get carried away.

You need to change your reference from a how much power for this and that bla bla bla to a reference of actual tested +/- improved performance by trying different stuff like lash and rockers.

That cam is small as cams go and will probabily respond well to running less / tighter lash than spec valve lash if you want horsepower.
less lash results in increased running valve duration. (makes the cam act slightly "bigger")

Your insane.

I get guys who do this and then want the $6000 trans under warranty.

You slip the clutch. The disc is cheap, and easily replaced.

most racing clutches won't "slip" they're not designed the same as a street clutch and go from nothing nothing nothing... bam, locked! That of course is for really high hp drag clutches.

Why are you running a split duration camshaft? Planning on running NOS? Here is my choice if; you have ported heads and headers, 180885-10NA 278/278 225/225 .525.525 110lsa 106 Hyd. You will also need a pcm tune.

Guess I should of read further back but there is still the split duration.

look at the heads,,,

[vinniekq2]

if you dont know the flow numbers red
227/155
68.3%
with a less than 70% exhaust flow ratio you still wont ude a dual pattern cam?
