![]() Well, I've been working on the 87 abit lately, and I've discovered a question: What kind of cam should I install? I'm planning on GT40 aluminum heads, GT40 Intake Manifold, 65mm TB, and 1 5/8 headers+ a hotter cam , which I would greatly appreciate your feedback on. I have been advised by many to go with an E303 and 1.6s, and by several others to go with a F303. I'm not looking to have a serious drag racer here, just a street racer with some extra power..
I would really appreciate any and all feedback. Thank you, Sac68 ------------------ 98 Mustang coupe 3.8L V6 87 Mustang GT hatchback 5.0L V8 87 Bronco XLT 4bbl 351W My mom drives a 99 Mustang GT convertable.

![]() They are probably some good choices. However if you can get some flow numbers for the cylinder heads. I would get those and give as much information to a cam rep as you can. They should have a pretty good reccomendation. I'm building a 347 and called Comp Cams. They're suggestion for mine was a Nitrous HP cam. Funny thing is I'm not running any nitrous
![]() BTW anybody know someone in Virginia that can dyno an EFI engine? (not chasis dyno but engine dyno). |

![]() Stock cam is around (211,115lsa,.444")
THe E cam is the crane 2040 (220,110lsa,.498) THe crane 2031 cobra cam was made for this combo (214/220,112lsa,.513/.529), with 1.7 rr. If you use 1.6 rockers, go with the crane 2030 (216/220,112lsa,.533/.544)... essentially the same. These give you a little more lift, and the modest duration maintains cylinder pressure, so it'll work better with the speed density. Plus, the 112lsa has a broader torque band, so it'll be better on the street. You can get either cam kit (with springs) for $210... so it might be worth it to get the heads bare, and get the better manley race flow valves for $195. If you're not gonna blow it, definitely increase compression by some milling... 0.030" = 0.5 more compression. You might consider some cheaper Explorer/GT40P iron heads too... more compression, more heat retention, and smaller ports/runner = high flow velocity, and good low end performance. ------------------ '89.5 5L LX, hatch, Medium Canyon Red, 155K Km (No winters), 5sp, 3.08, GT interior, a/c, Alpine CD, K/N, Crane PS91, Walbro 190 LPH, March Pulleys, Mr. Gasket 180 therm (HP balanced), 3 core rad, MarkVIII fan, Variflow controller, Polygraphite front bushings, FMS-5300B springs, 6 KYB's, 73mm Calipers, Maximum Motorsport 4pt chassis brace, Western Motorsport Racing's Sub-frame connectors.

![]() Thanks to everyone for the feedback, its greatly appreciated.
Damn, 3 different suggestions... Skankin, you say that the crane 2031 was specifically designed to work with my planned combo and 1.7s? That sounds like a winner right there. Thanks again, and any further info is still very welcome. |

![]() I like my combo a lot and I would recomend it. With the B cam and 1.7's your lift will be 514 and that cam has a nice meaty duration. Its realy close to the F cam in comparison with those rockers.
