parts have been improved since the OP.....maybe time for a update?

 

Has there been any significant improvements worth noting? I'm only asking because I was thinking that surely there has been improvements made in some areas

I realise that the forumla to make this kind of power is careful planning and the best parts money can buy

Would there been much of an increase on Pat's original setup with the Fast 102 manifold setup?

 

Keep in mind that very little of this combo was actually comprised of "off the shelf" parts. Improvements have been made to the heads and intake used, and some different lobe profiles are available now. Would any of these significantly change the output?

What I have read of the FAST 102 is that several of the shortcomings have been addressed. For a guy who can't or won't pony up the bucks for porting, that means his results would be better than the same setup with a box stock FAST 90/92. It's hard to imagine the TB as the restriction here at 347ci when guys are running the same manifold on 408+ engines.

Much of the same can be said about the updates in the AFR line of heads. The key thing here is max attention to detail. Tony Mamo didn't leave much on the table when he hand ported the heads and intake for Pat's setup. What has occurred in the last three and a half years is a boon for the consumer. With out of the box parts and attention to detail, you might very well get 95% of the results Tony and Pat were able to achieve and at a significant discount when you figure what Tony's labor costs.

As for cam lobes, I imagine the same valve events ground on EPS lobes could make more power through slight improvements in stability. Again, there wasn't much left to improve as Pat has been setting up more aggressive XFI and LSK cam lobes for some time.

 

i am still wanting to see someone make 500hp with a stock bottom end LS1 on the new LSL lobed LSR cams. i am looking at the 231/239 .614/.624 113 LSA cam and hoping to make 260+ with PRC heads.

 

Fixed..just didn't want anybody to get confused...... LSR cams use LSL lobes...

 

thanks, fixed

 

260+ whp??? with heads and cam plus your fast 92?

 

if i had a m6 would be 15-20hp higher...

lsl/lsl lobe cam (speced by Patrick G)

 

^ I'm getting a little closer with the 102 swap.

I've been using this as my bible since I first read it. It's my end goal to extract all I can out of this cam. (PatG cam)

 

click awesome write up!

 

so is the cam that i cam getting (227/235) gonna put me at a very nice rwhp number with 5.3 heads.

also chris, are you using stock rockers or roller rockers?

 

subscribed!

 

Pat, what size pushrods did you end up with? Not the length, the diameter?

Thank you-

 

Would there be more power to be gained from this combo if it was tuned on E85? Would it be worth swapping to E85 or would the gains not make it worth while?

 

If I remember correctly E85 has the potential to produce 9-11% more power with the same amount of air, so I guess it should produce more

 

We used stock diameter chrome moly pushrods at the time. The larger diameter Manton pushrods would certainly be worth considering though as they improve valvetrain stability with really stout spring setups. My 500rwhp combo ran AFR 8019 springs which are equivalent to Patriot Extreme Gold Duals which are very common these days.

 

Several in our area are running E85 on LS1 and LS2 engines, including myself.

2-3% power and 3-5% torque have been typical. If you are within 10-15 HP, then it could help you reach your goal.

The 9-10% referenced is likely related to the FI crowd...the cooling affect of E85 tends to provide bigger gains for them.

 

keeping this one for later

 

can you build a 500rhp ith a ported vic and accub4150 track only car wt350

 

On the rod bolts again. Since my post was closed and this one is allowed to continue... How do you resize rod bolts?
I'm debating on ARP, but there is two different types. Hi-perf & Professional series. Anyone know the difference?
If resizing is too much work I may just go with the Katech's but I can get the ARP's cheap where I work.
