Considering a head swap, suggestions?

[ForcedFirebird]

Would the trigger on the store work for a RWD setup?

Looks like it, as long as the bolt pattern in the gen3.1 crank is the same (if not, that trigger could be easily modified).
Thanks for the heads up.

I have a 2.8 block.

3.4 blocks are expensive around here, it was much cheaper to build this crank trigger, whihc is also adjustable, than to spend $1000+ for a block, since I'd have to buy the complete long block, and all I needed was sthe block itself.

I guess what I am asking is if the 3.4 trigger could be used on the 2.8 or 3.1 block?

Again, you never cease to amaze me. What stopped you from using the 3.4 trigger? I have a friend that works in a CNC shop who is also a tool/die maker who's been helping me make parts. In fact, here's the flanges he made for boostedrs' manifolds...

Could you enlighten me? Did YOU make the trigger, or adapt one from something else?

Made it. It was a colaboration between myself and my Grandfather, he's a Tool and Die maker by trade, though retired.

The genIII timing wheel behind the balancer is NOTHING like what you need to run teh coil packs.

The coil packs need a 7x reluctor, while the balancer mounted wheel is a 24x.

In this first pic, the notches were not cut, this was before the engine was installed.

Actually had the front of a 4th gen Camaro apart today. It looks to me like using the 3.4 gen timing cover, you could have used the pick-up sensor. Just don't know if the gen1 3.1 crank needs provisions for the wheel.

[ForcedFirebird]

Yep, I did.

Custom external crank trigger FTW!

Sorry, what I meant is can I go with a distributorless to eliminate the problems with dizzy clearance.

The genI 3.1 has a dizzy, in fact the genI 3.1 is pretty much a carry over of parts and design, juts like the genII 3.1 is a so similar to the genII 2.8.

Once I get a bit more time, I'm going to be modifying a dizzy to clear the genII intake and fit under the hood, well under the cowl actually. My trucks dizzy is under the cowl area, or at least partially under that area.

My initial dyno numbers are in my sig. The numbers will be MUCH higher when it comes back out, there were some issues with tuning back then, and wome other things I learned from that build that will be changed to increase numbers somewhat easily.

When the pistons get here, I'm curios to see if they also could be machined to help lower compression a bit.
The short block in the car now is in great shape, so the piston/head combo is staying with the exception of P&P along with one of boostedrs's UIM and one of the 75mm TB's from ryan hess. Also just ordered a mild reground turbo cam (.440/.440 212/212 @ .050 112 LSA Adv Dur of 260) that will be going in soon.

Stock 3400 heads with camaro 3.4 pistons should give you 11:1+ compression. Depending on the boost level, I think that could be very interesting.

What about 3400 heads on a .030 3.1 with RWD pistons? The motor in the car now is staying iron headed, but I'm looking for a good block to work over to do a swap later.

To do that with a 3400 upper would require a lot of porting but I am not sure if you can fit a 3500 plenum (without lowering the engine).

I'll have to see how much room there is under the hood with the stock engine in there. I'm also going to have to figure out a way to keep the dizzy. boostedrs was able to mod the dizzy to work, but he has a cowl hood that gave him extra clearance. Maybe in the future I could end up going with a cowl, but kind of want the car to be in "stealth mode " (not to mention the 4th gen t/a hood I like is over $800).
Does anybody know if the gen1 3.1 can be modded for a DIS (I've heard the 3.4 has provisions)? And are there advantages over a dizzy?

At .040 on a 3400 block, I measured 12.4:1 using 3500 heads with work and stainless valves (31.7cc vs 32.4 stock 3500). Stock 3400 heads are 28.x cc but ported how I would do them for boost, they would be roughly 29cc with stainless valves. I mention the valves because they increase compression over stock valves. The 3400 top end has the most flow potential using available gaskets/parts but you need the 3500 plenum to pull it all off. To do that with a 3400 upper would require a lot of porting but I am not sure if you can fit a 3500 plenum (without lowering the engine).

I would def do a head swap.

I haven't seen any dyno numbers from boostedrs on here or TGO, if there point me a link. Tiago (that was who I was trying to think of), has proven dynos numbers a few times over, along with a vid, that I lost from when my laptop crashed.

I thought I knew who you were! I found some old threads from Tiago on cv6/fbv6, amoung a few others that could pull the wheels off the ground N/A with sub-15's in the 60*. This is my first v6 project and think I'm going to have some fun. Ordering MegaSquirt this week, and the cam should be here by Fri. Six_Shooter, you have that 3.2 dynoed at how much? And YOU were the one who mentioned the high SCR is good with boost . I just want to be able to get by on 93 octane pump gas or up to a 50-50 race/pump mix(probably just for the track with the boost turned up).

I thought I saw his numbers somewhere, but I guess it was only in his sig. I've seen videos of 4th gen V6's making 400 but with the 3.8
What kind of times was Tiago getting in the 1/4?
