Opinions on my motor combo

93cobra1928 · 03-10-2009, 06:52 PM

Just wanted your thoughts on my motor combo. Suggestions for improvement, etc..

306cid, DSS forged flat tops, X-303 cam (installed dot to dot now, was 4*adv which put the intake centerline @ 101*), World Windsor Sr heads-milled to 62cc ish 2.02in 1.60exh screw in studs w/ guide plates and 1.6 roller rockers, stock bottom end with ARP rod bolts, stock 93 Cobra induction (65mm tb, 70mm maf, 24lb/hr injectors, GT40 upper and lower, stock fuel rails and regulator) 190 lph fuel pump.

It has a 1" spacer on it to clear the tall valve covers- this is coming off
I will be installing new efi valve covers (FMS-M-6000-C302) partly because I want the stock hood back on it and I think the spacer is hurting me and possibly contributing to idle surge

Fire away, all coments welcome

ditch the cobra intake, look into a larger MAF and t/body. (I ran a PMAS 80mm MAF and a Accufab 75mm t/body on my last n/a combo)

In case you have not already seen it, here are the different combos I put my cobra through

Thanks. What do you think about the cam timing-leave it alone or move it back to 4* adv?

This is a street car that might see an occasional test and tune night

QWKSNKE · 03-10-2009, 07:09 PM

leave it alone.
Reference my edit in the above post too

I would definately like to put an RPM on it, but I will have to make do for now.

My first outing with the new motor felt pretty good but I was expecting more.

It needs a 3.55 gear really bad and once the spacer is gone hopefully the butt dyno will see a big change

tayzoid1 · 03-10-2009, 07:33 PM

what kind of hood do you have on inquiring minds want to know?

QWKSNKE · 03-10-2009, 07:34 PM

What gear is in it now? The stock 3.08? Unless you have 3.55's already laying around, go with 3.73's. They would suit your current combination better.

Personally,I'd have the heads milled to at least 60 cc's,if not 58 cc's,unless you're planning on adding boost in the future.

93cobra1928 · 03-10-2009, 07:41 PM

tayzoid1, right at this moment none, I had a 4" cowl on it but that went back on the coupe I'm selling and I really didn't like the look of it , thought about a 2" cowl but like the stock look on the Cobra

QWKSNKE stock 3.08 now, I was thinking 1st gear would be useless with 3.73s but then again I have never had that in a 5 speed car so IDK

I would love to add some boost at some point, say a 10lb Vortech
