Hi,
Bit of background, have owned a '86 z51 coupe last 15 years, recently the intake manifold started leaking, so I started taking it apart to replace it and "while I was in there" you know the story.

Anyway this is what I am planning

HSR intake
Ported 113's
1.6 Roller rockers
1 3/4 LT's
2800 stall
3.07 rear

Have not pulled the engine yet so not sure what the bottom end looks like but its done 120k miles so may need a bit of work.

I was looking at the one of the cams below, would they suit, its mainly street car (not DD anymore) with odd run down the strip

Thanks

In my opinion, no. They can work, but both are huge.
If it were my car, I would look for the following:
Int duration @ .050 224
Exhaust duration @ .050 230
Intake lift .550 with the 1.6 rockers
Exhaust lift .550 with the 1.6 rockers

Lobe seperation 112

I would not go flat tappet cam, and would do a roller conversion.
In my opinion, flat tappet cams should be obsolete. Without zinc in the oils, the risk of break in failure is not worth it.

I agree those cams are pretty healthy for a 350 street car, if it were me I'd wait and see what I'm doing w/the bottom end, and what the heads end up at w/numbers. At that point (depending on rebuild cost of original short block)you may want to consider that crate 383's go for reasonble money these days.

I wouldn't thrown $$$ at those 113's

There's a ton of CNC'ed heads on the market nowadays that will outflow what you can get out of them.

I agree with the cam recommendations. Plus you will get more from headers in the rpm range you will be using with 1 5/8" primary tube headers rather than the 1 3/4" you mentioned.

RACE ON!!!

I ran an XFI 280 in my 350 for awhile and liked it. It's a little more along the lines of the cams you posted, but not quite as aggressive.

230/236
.571/.565
113 LSA

You'll have to work on the guides of a stock 113 head to keep from pushing the valve retainer into the head, but if you are machining the heads anyway it's not too big of a deal.

Hi Guys,
Thanks for the response, I am in Australia so options are more limited than US and generally more expensive.

I did think about replacing the heads but seemed to get expensive real quick, same with the roller cam conversion.

Re the headers I have only seen 1 3/4" listed here (car is converted to right hand drive) but will have another look.

Hopefully I will get the engine out in the next couple of weeks and see what its like.

Josh, what was your setup when you ran the XFI 280 ?
