Guest Anonymous Posted October 18, 2001 Share Posted October 18, 2001 Hello,well after waisting hundreds of dollars on the stock L6 I have now realized I want to put a 350 in my car.I have a couple of questions,my car has Eibach pro kit with tokico struts all new urethane everything.Will this suspension setup hold a 350?I also have new floorboards from motorsports will the frame rails hold the motor?I have a 350 from 1989 chevy van with an automatic in it can I use a 5 speed with this motor?If so which one?Where can I get headers and what kind should I use?Thank you .

DavyZ Posted October 18, 2001 Share Posted October 18, 2001 The suspension is perfect for the V8 swap. If you decide on upgrading to aluminum heads and intake manifold, you'll be very close to stock weight! Are your Eibach's 200 lb rate or higher? Good, no problems then. The 1989 engine will work with a T5 from a Camaro--just make sure you get a 1988 or newer T5 since they are WC (World Class) units that have improvements over the old units. If you are going to be drag racing this car on a regular basis, you will want to get a T56 (6 speed) if you want the stick shift. I'm not sure what you mean by "the frame rails holding the motor?" The crossmember holds the motor. I suggest buying the JTR manual and reading it several times to get a very good idea about what all goes into a swap and the time involved. Also, use the search function in the forum to find out information. In all probability, any question you ask will have been answered multiple times. As far as headers, you will need block-huggers. These are made by a number of different manufacturers and have different prices/quality. I would venture to say that most "blockhuggers" for a SBC will work. If you have aftermarket heads, sometimes sparkplug boot issues may arise, but most guys here don't have any problems. I bought cheapie Summit Racing headers for $70. Good luck with your project; I don't think you will regret it. Davy Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 18, 2001 Share Posted October 18, 2001 What I meant by frame rails is I have a friend of mine that I was talking to and he said that when he had first put a v8 in his 240 he twisted the frame rails,but I just talked to him again and he explained that he has a 400+hp at the rear wheels and that this was the cause.Thank you for the info.

Guest Anonymous Posted October 18, 2001 Share Posted October 18, 2001 For you that have done the swap is there an aftermarket wiring harness or should I just use the stock one?What about the ac compressor? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 18, 2001 Share Posted October 18, 2001 Much will be answered just with the JTR book, however, the stock wiring harness works, ok, but if you have the time and money, you wouldn't regret putting in a Painless wiring harness at the same time. As for the A/C compressor, psych it out by making a bracket to hang it on the chevy engine. Most compressors were used here Domestically in one application or another, so finding a bracket shouldn't be very hard. At any rate, hung on the chevy motor the AC compressor won't know the difference and the car will remain cool. Regards, Lone Quote Link to comment Share on other sites More sharing options...
DavyZ Posted October 19, 2001 Share Posted October 19, 2001 5th, he's talking about twisting the chassis--yes, that can happen, especially if you drag race the car and/or have very high hp. A rollcage or good rollbar will do a lot for taking out chassis flex. Also, there are things called subframe connectors that will go along way to helping to eliminate this problem. Check out Pete Peraska's site for a drawing of subframe connectors--the hard work has already been done for you! Davy Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted October 27, 2001 Share Posted October 27, 2001 5thGear, You mentioned using a 350 out of a Van that came from the mfg w/an auto trans & asked if you can run a 5spd manual trans. Be sure when you seperate the eng & auto trans that you confirm your crankshaft has a recess in it that will accept the input shaft from the new 5spd as that recess is where the pilot bearing rests & the input shaft nose fits in the center of the pilot bearing/bushing. Some crankshafts whose engines were hooked up to automatics were not machined w/this recess in it-therefore if you plan on using that crankshaft & it doesnt already have the recess you will have to have one machined-I had to do this once w/an Olds 455...it cost me about $100. Just FYI! Kevin, (Yea,Still an Inliner) Quote Link to comment Share on other sites More sharing options...
