So I originally built my forged 13.2:1 compression 385 2 years ago, running E85 with a custom LE cam (24x/25x .61x/.62x 110), planning to use LE 21* TFS heads and ported intake, but as things usually go with builds, costs started exceeding budget, so I ended up sticking with the 185cc EB Porting heads and stock intake I used on my mild LE cammed stock block. Now I've finally upgraded the top end to AFR 210 Comp Eliminators with Manley Nextek beehives and a ported LE LT4 intake, which drops compression slightly to 12.5:1.

Never dynoed the old setup but it ran consistent 92mph in the 1/8 with a blown pass side exhaust gasket and mail order tune. Should have it back together this week, any guesses what I should expect with a proper dyno tune on this new setup?

You looking for track times or dyno numbers?

Since its an autox/RR car, and the fact I'm still on the 10-bolt (for now) its not setup to launch hard at the strip, so more along the lines of guesses on track mph and rwhp. I'm assuming I'm going to notice quite a bit of difference especially on the mid-top end?

So finally got it started this morning, and went on a little cruise. It pulls HARD, especially mid-high RPM. Here are a few pics and the startup video.

I guess posting the album didn't work, here are the pics and first start vid.

Awesome stuff should mph pretty well in the 1/8. I would assume Atleast 96mph

Top end improvement will be massive going from 180cc ported stockers to AFR 210s with that 24x/25x cam on a 385.

I could see 95-96mph traps now as well.

I'll say 98-100 mph traps, unless the car is awfully heavy.
You should be pushing~600 crank hp.
M6 hurts the leave, but more than makes up for it in mph as you get down track.

That's what I'm hoping for. It does pull MUCH harder than before, pulls hard all the way up to my 6800 limiter, whereas before it kinda leveled off around 6k with the smaller heads/stock intake. Might bump the limiter up to 7k now, since it can breathe up top and has the Manley beehives. Unfortunately I burned a plug wire (forgot to zip tie it out of the way), so I need to order a new set.

IMO, no. Just another failure item. I ran about 660 fwhp on mine with the nitrous on bone stock ignition just fine.

Gotcha. What about the MAF? Is the stock screened MAF a restriction for 7000 rpm on a 385?

I don't know how much the screen restricts, but de-screened stock MAF's support 600+ hp (flywheel).

Ok good to know, thanks!

Here's some numbers from Myron's lt1 book:

Stock MAF 529 cfm
Descreened MAF 711 cfm
Ported and descreened MAF 750 cfm
