Looking to add another bolt on.. mod.. What bolt on should I go with next.. going for a sleeper/dare to be different build for now untill i get my custom cam and tsp as cast heads. Trans will be built soon from RPM (lvl5) with a decent converter. My trans is my highest priority.
I have a few options:
TPIS 90mm intake setup w/ z06 maf and FTP 98 Lid and 90mm nitrous outlet plate
^already have spare ls6 intake, z06 maf
1.85 rockers
I need to buy the rockers, hardened pushrods, and springs
AI ported High compression 806 heads
need head gaskets, studs, bolts
Electric water pump
Underdrive pulley
need bolt and belts ect
Carbon Fiber driveshaft
open to suggestions, trying to prioritize right now

the roller rockers probably won't work with the new cam, most cams are meant for stock ratio rockers
why buy expensive ported heads now then replace them again with TSP heads?
electric water pump is very poor $/hp mod and I still trust a mechanical more than electrical personally
carbon fiber driveshaft is a beyond poor hp/$$$ mod
You could do the pulley but it will have to be done again during the cam install anyway, not sure how difficult it is on a fbody, if it's easy it might be worthwhile. Used in good shape is better hp/$$ than new.
The TPIS ls6 intake has never impressed me for the cost, but if you have an extra intake already it might be worthwhile...I would rather sell both intakes you have and get a Fast 90mm any day of the week though. The MAF will need a tune and net no noticeable power.

I'm using the z06 maf mostly because im not wanting to do a speed density just yet. If i can come across a fast 90/92 I will jump on it, but I've seen dynos where they net the same HP.. and the TPIS gaining more torque.

The way i was looking at it, i have a spare ls6 intake handy, costs 350$ to get it converted, gain similar results with very good upside. However, if i get a nice fast intake I can hold onto it and get it ported and have even better upside. Ofcourse that costs alot more $$$, no idea what a used fast would cost.. im assuming about 700$ +/-? then to get it ported another 300$, ehh i came to the conclusion the TPIS would be a better intake mod for now.
I was considering a RR/HC ported heads combo, I seen a few heads only w/ RR results pushing the 400 barrier. I'm keeping the stock RR's for when i switch over to a cam.
The driveshaft isnt meant for a HP perspective, but i hear its good for .2's off a 1/4 with a nitrous setup, and easier on the rear, and when u go to the track u dont need a DSL.. i got true duals and its hard to find a nice dsl for my car. Yeah its expensive tho..

I got my Fast for ~$500 used which was a good deal but if you poke around you should still be able to find one for a good price. I did some porting to mine similar to the porting the cheaper port jobs would be. It was very easy to do if you have a dremel, some sanding rolls, and patience.
Even if a used Fast is $700 and that's the best deal you can possibly find: 2 ls6 intakes @ $350 each = Fast intake. It should also retain more resell value than the TPIS in case you ever step up to rectangle port heads or something of the sort.
I don't doubt the TPIS might make good power, but the rare results I see where someone tests one seem to be even more hit or miss than the Fast intakes which already seem to vary a lot in HP gains.

what are your thoughts on a 160 degree thermostat?

I'm undecided, I kinda want to put a 160* in mine with hopes of the thing not running at 205* all the time. It ran 196-198* all the time no matter what before I did the head swap, now it runs a little warmer.
I'm just worried a 160* might let it run too cool (big Chevelle radiator). The 180* thermostats seem to be harder to find and more expensive last time I looked.

All I really did was take out the large wedge in the runner and blend it all the way through the rest of the runner and take out casting flash and places where the pieces of the shell didn't match up perfectly.
I have a thread somewhere but the pic links might be broken by now. If you pick one up there a couple good threads on here for the porting and I have my pics somewhere I could send you too. I found some other places I could have worked on too after the fact.
Might not be up to par with a Mamo port job or anything, but it made me feel like I was accomplishing something and I like being hands on...
