What should I look for in shop that will do the fresh bore, suggestions, do and doníts, weak points that should be addressed to avoid engine failure, things i should greatly consider doing in this process? Any help, advice, expertise, or insults are greatly welcomed!
Block is a 400 from a 1970 Bonneville, 1970-16 heads (small valve I believe) Intake manifold is from 1975. My friend and I were in the process of getting the car on the road, when come to find out lifters were bad and had a bent pushrod. We tore the block down and inspected everything, which looked to be in good shape. Cylinder walls look to be in good shape as well. I purchased a re-ring/seal kit from summit as I was under the impression everything was good to go, just needed to clean the sludgey nasty up, and purchased a new cam, lifters, and pushrods and paint it back to blue. Once, we got ready to begin reassembly, we found #1
piston heads had cracks where the rings went.
I have been all over forums and such and reading about flat top pistons, CR, heads, crap pump gas causing detonation, cams, etcÖ This is my first Rodeo and I have literally read myself into a cold sweat and lack of sleep, because I donít really understand how to tie it all together and create a reliable power plant. My friend who is graciously helping me with everything, has built some fine examples of high HP Ford motors in the past, and itís not that I do not trust his judgment. Actually, I feel like a 4 year old that has just too many questions.
He suggested having the block bored over .030, since we need to purchase new piston heads anyways, and with a fresh bore it will be an extra piece of mind, give me a bump in power without rendering everything I have already done obsolete, and allow me the confidence that itís not going to go boom one day (as long as I donít abuse it). I only ever planned to run 93 octane. I have a brand new summit cam with duration 288/298, Lift .444/.466, and honestly everything is newly rebuilt or brand new, minus block/pistons/crank/heads.
Iím already hemorrhaging $$ on this car, as I like to do things the right way and because I was bamboozled by the family member I bought it from (weeeee!). My plan for the car is just a fun street cruiser for a while that can tear the tires up. Originally, i wanted an 11ís street car, but thatís far down the road now, and Iím just concerned with actually being able to drive it before judgment day.
Thanks for any help!
