for starts i have a 91 tbi 305

In my haste when ordering tuning parts from moates i ordered the wrong chips and i didnt realize that i needed an adapter and a ziff....well u learn so my ignorance has caused set backs, its life.

my problem is that my l03 was having some bearing issues so i pulled it out and i got an l05 out of a wrecked truck for free, it only had 28k on the clock. but i couldnt stomach putting an engine with just as much age in even though the miles are much lower so i sent it to a shop that i have a lil of a hook up to have seals, bearings and the rings replaced, and they guy called and told me the money i was spending also covered getting a new cam set installed and he asked me i wanted stock or aftermarket, well i said gimme the biggest cam u can get with out any interference problems and he said he would check the book and do it.

if you cant already tell where this is going, im curious if the car will start
when i drop the motor in and how bad it will run, i have been unable to get a hold of the guy but all i know is that he is putting the most radical cam he can without causing problems. I will tune it up when i get my stuff in tho

 

Heh, I suggest getting ahold of the guy. He puts a big enough cam in it, and it will not start or idle at all depending on your head/intake/etc setup.

If he's not too bright, he might even put in a cam which is too large for the heads. You can either pull a rocker stud or break your valve retainers that way, the latter of which can/will ruin the block. Definently check the cam specs before you even turn over the motor and make sure your heads can handle it.

 

i just got the cam specs along with the engine today and I am hoping that someone can let me know if there will be tuning neccasary for it to run, i know that for it to run at its full potential tuning will be required. Im looking at the info and from what i know about cams in general that it isnt all to radical.

Crane Cams Energizer 100042
Lift: .440''/.440''
Duration: 266°/266°

 

Hey Jeff

That cam 100042 has duration 210 int./210 exh. at 0.050 lift with LSA of 110 degree. Due to a narrow LSA angle this cam may not be a good fit for a stock TBI engine. Small LSA angle will cause intake charge to flow (during valve overlap) through and may confuse (due to extra oxygen present in intake air-fuel mixture) O2 sensor at idle if close loop idle is contemplated. Instead, I would look for cam with LSA 112 and higher given a stock engine configuration. Crane states that 100042 has smooth idle, daily driver for 8.5 to 10.0 compression and it is 50 state legal for pre-computer applications, C.A.R.B. E.O. D-225-21. This would be a fine cam with one exception for LSA. Instead take a look at cam with somewhat wider LSA angle - Crane 11432 is one of many examples which has a basic operating RPM Range 1,600-5,400
I/E @ 050 inch Lift: 210/216
Advertised I/E: 270/276
Valve Lift with 1.5 rocker 0.440 int./0.454 exh. lift
Lobe Separation (degrees): 114
It is a high performance cam - there is no doubt about it and according to crane website:
GREAT FOR 305 HO, PERFORMANCE 350 TRUCKS AND TPI-EQUIPPED 350 ENGINES. GOOD MID AND TOP END TORQUE AND HP. AXLE RATIOS OF 3.73 OR NUMERICALLY HIGHER REQUIRED. AUTO OR 5- SPEED MANUAL. MUST USE ADJ. FUEL PRESSURE REGULATOR. (50 STATE LEGAL IN 81-87 267-400, CARB EQUIPPED CARS ONLY. C.A.R.B. E.O. D-225-25) BASIC RPM 2000-5000.

Both CAMS can be made work with TBI with a little bit of tunning.
