rudypoochris Posted September 13, 2006 Share Posted September 13, 2006 Here she is: Do they sell headers that will fit? Or based off these pictures do you guys think I need to obtain custom exhaust manifolds. it is particularly tight near the starter (which isn't installed).

b__sosick Posted September 13, 2006 Share Posted September 13, 2006 either "block hugger" style headers, or you will need custom headers to fit. Quote Link to comment Share on other sites More sharing options...
rudypoochris Posted September 14, 2006 Author Share Posted September 14, 2006 I am a bit concerned with the whole exit area of the exhaust. I am not sure if headers designed for the mustang will let out in the right area. The pipe might have to go a little forward compared to the Mustang outputs.

alsil Posted September 14, 2006 Share Posted September 14, 2006 You're right, the Mustang headers won't work, they will hit the firewall on both sides. You have to use Block-huggers, which seem to fit nicely. Besides that, you can have custom long-tube headers made to fit also. Quote Link to comment Share on other sites More sharing options...

Challenger Posted September 14, 2006 Share Posted September 14, 2006 A friend of mine has a 302 in a pinto wagon and he has the same issue with the headers. I found a header brand that might work, they make headers for 302 pickups but im not sure if they work for older 302's. The header was called Jba cat 4ward, hopefully theyll work.

Dp351zcar Posted September 14, 2006 Share Posted September 14, 2006 You might try summit #SUM-G9063 The are shorties and I bent the right side a little and bolted them on the left side and it clears the steering shaft by just a little. The left side bolted on the right makes it clear the starter and might come out in front of the crossmember motor mount. It's worth a try.

jbk240z Posted September 14, 2006 Share Posted September 14, 2006 That is all the room that is in front of the enigne for twin turbos, plumbing, intercoolers, etc. I'd say get a pair of shortie headers, install upside down facing the front, add twin turboos and hold on tightly! Check the following link for a low-buck easily done approach to said ideas. http://www.toohighpsi.com Good luck on ur Z! Quote Link to comment Share on other sites More sharing options...
Just Jim Posted September 14, 2006 Share Posted September 14, 2006 My 302 install looks similar. Summit street rod headers worked good , cleared the steering shaft just fine but require a smaller PMG starter. http://store.summitracing.com/partdetail.asp?autofilter=1&part=SUM%2DG9063%2D1&N=700+0&autoview=sku I got a small starter on E Bay for about $60.

Wow thats sweet! I might just have to order some of those! Also out of curiosity how did you fuel it. My stock mechanical fuel pump hits the steering shaft since the block is too low. We are thinking of going with a 14psi pump that flows something like 140gph and then putting in a return regulator. 3/8" fuel and 5/16" return.

Just Jim Posted September 14, 2006 Share Posted September 14, 2006 I hooked up a Carter electric pump near the tank and used the stock 5/16 line with no return line. The pump puts out about 7PSI and requires no regulator. The same pump fuels the 351 in my Falcon which runs high 11's in the 1/4 with no fuel problems. http://store.summitracing.com/partdetail.asp?autofilter=1&part=CRT%2DP4600HP&N=700+0&autoview=sku Quote Link to comment Share on other sites More sharing options...

Do you think my high fuel line will cause a vapor lock issue with the pump you are using? Do you ever have a vapor lock problem or never?

wheelman Posted September 15, 2006 Share Posted September 15, 2006 rudypoochris, Are you building a crossmember to brace the motor mounts? If not do a search through the old posts from guys who've installed mounts the way you have and read what they have to say about the stress placed on the frame rails. Alsil reported his started to twist from the engine torque so he designed the crossmember mount he sells. Wheelman Quote Link to comment Share on other sites More sharing options...
Just Jim Posted September 15, 2006 Share Posted September 15, 2006 Very intresting! Do you think my high fuel line will cause a vapor lock issue with the pump you are using? Do you ever have a vapor lock problem or never? The pump I used should work fine with your fuel line. Vapor lock was never experienced with my other car or the 240Z but the Datsun hasn't been driven much since the V8 swap. Usually vapor lock occurs when using an engine driven mechanical pump which is pulling fuel from a rear mounted tank. Rear mounted electric pumps pushing fuel to the motor shouldn't experience vapor lock. Insulating the fuel lines in the engine compartment wouldn't hurt though as it does get pretty hot under the Datsun hood. Quote Link to comment Share on other sites More sharing options...

Just Jim Posted September 16, 2006 Share Posted September 16, 2006 Nice looking valve covers. Makes me want to do the same with a similar set that were on my '83(?) H.O.. Wonder if those covers will clear roller rockers? Quote Link to comment Share on other sites More sharing options...
