Sam1647545489 Posted December 29, 2010 Report Share Posted December 29, 2010 Should I just strap a blower to my 350 or should I put a set of heads, cam, intake and carb on it. I wanna make close to 400 hp, both will cost about the same if I buy a used blower. Also the blower won't require me taking the whole motor apart. Thoughts?

I would say if you are planning on keeping the boat around for a while and will be sticking with a SB, I would build the motor first and build it for the blower. Actually, that's exactly what I did do. LOL Blowers do sound cool though and I do love the instant power. How well will your current motor hold up to the blower?

Guest 614Streets Posted December 29, 2010 Report Share Posted December 29, 2010 Resources. The Mini blowers typically add 100 hp at 5 psi. If you have Vortec heads you should be able to get close to 400 , what heads are on the motor now? Got to becareful buying a used unit , find out the miles on it and for things like play and damaged rotors. If you could find one of these used , they look like a good mini. http://www.carcraft.com/featuredvehicles/116_0609_supercharged_350ci_chevy/index.html The 142. http://www.holley.com/data/types/pictures/142_SBC_ZOOM.jpg http://www.carcraft.com/techarticles/ccrp_0606_supercharged_small_block_chevy_engine_build/index.html http://www.carcraft.com/techarticles/ccrp_0606_supercharged_small_block_chevy_engine_build/index.html http://www.chevyhiperformance.com/tech/engines_drivetrain/shortblock/0901chp_1972_chevy_nova_weiand_142_blower_upgrade/index.html http://www.chevyhiperformance.com/techarticles/46461_gm_350_crate_engine_build_vii/index.html http://www.superchevy.com/tech/0307sc_mini_blower_mouse_engine_test/index.html Quote Link to comment Share on other sites More sharing options...
Sam1647545489 Posted December 29, 2010 Author Report Share Posted December 29, 2010 Will, the heads are just stock iron heads. The motor is pretty much stock with a lil better then stock cam. I thought about doin a top end rebuild with vortex heads, bigger cam and better upper parts, but I dunno if I wanna tear into the motor yet.

Yeah I know, but since I prolly won't have a car this summer, I will take my modding itch to the boat. 400 hp is all I am looking for.

Sam1647545489 Posted December 30, 2010 Author Report Share Posted December 30, 2010 Haha, tell me about it. I decided to go with a set of jegs aluminum heads, a roller style camshaft, MSD ignition, intake and prolly a 600 cfm carb. Should net me another 75-100 hp plus allow me to spin the motor alil higher. 23 pitch prop and I should be anywhere in 65-70 mph range.

wnaplay1647545503 Posted December 30, 2010 Report Share Posted December 30, 2010 Mod it til it breaks is not the scenario you want to have when you only have a few months a year of enjoyment. Cars have the majority of the year to still get fixed and enjoy. Plus easy to get parts that can be found 10 mins from almost anywhere.

FormulaMatt Posted December 30, 2010 Report Share Posted December 30, 2010 What cam and head size did you go with? I'm not sure a 600 carb is enough. Boats are different then cars in this aspect. Quote Link to comment Share on other sites More sharing options...
Total Sign Posted December 30, 2010 Report Share Posted December 30, 2010 You will need a bigger carb. What are the cam shaft specs and head specs? Quote Link to comment Share on other sites More sharing options...
Sam1647545489 Posted December 30, 2010 Author Report Share Posted December 30, 2010 I haven't picked anything out yet. I was just stating what I was gonna buy. There is a 650 double pumper I could get. I don't want to go with to big of a cam but I want something decent. The heads are just the Sbc aluminum jegs brand heads listed on their site. The carb can be whatever. Quote Link to comment Share on other sites More sharing options...

Cool, we are just making sure you don't regret your choices and have too buy things more then once. Or, that you have a setup that doesn't work well together. On the cam, post up which you are thinking about. Or research it on some of those boating sites I gave you. If you ask for input from someone somewhere else, make sure they know you have a stock exhaust. Without changing exhausts, reversion can be a huge issue with too much cam.

FormulaMatt Posted January 4, 2011 Report Share Posted January 4, 2011 hows yours running? Ran great at the end of the season after the drive swap. Still need to try a bigger prop. I can put my 21p Mirage to at least 6k. It would have kept going, but I didn't let it. I really need to try a 23-25 something. She's asleep right now.
